The Täufer Lehrer of Ober Kneubühl: A Legacy of Defiance

In our family tree there are many, many stories of courage, faithfulness, resistance and perseverance. But few rise to the level of my 8th great-grandfather, Durss Aebi, a Täufer Lehrer--Anabaptist Teacher--who followed his conscience with a stubbornness and spiritual conviction that defied the most powerful government in Switzerland. 
 

Childhood in Ober‑Kneubühl

Durss was born about 1610 in Ober-Kneubühl, a small hamlet tucked into the upper Emmental region of the Canton of Bern, Switzerland. He was the eldest of eight children born to Ulrich and Elsi Aebi. Although no records of his childhood can be found, the history of the area during that era allows us to imagine what his early life would have been like. Homes and barns were built of massive square timbers designed to withstand the brutal alpine winters.  Families lived in multi-generational households, so he likely lived not just with his parents, but with his grandparents and aunts and uncles as well. 

Although many families in the region farmed.  The Aebis were millers, grinding the local spelt and rye into flour.  His childhood would have been shaped by the thundering splash of a waterwheel, the clacking of wooden gears, and the rhythmic grinding of heavy millstones. Unlike farm children who saw few outsiders, a young Durss would have seen everyone. Farmers from across the Sumiswald hills would have come to the mill to turn their grain into life-saving flour. He would have heard the adults swapping local gossip, complaining about the Bernese government's taxes, and debate theology while waiting for their grain to be processed. His chores would have shifted from minding cows to mechanical and strenuous work. He would have included lifting heavy grain sacks, managing the water gates, and maintaining the mill’s complex mechanics.

 As millers, the Aebi family would have likely been more financially stable than tenant farmers. They would have kept a percentage of the grain they milled, giving them better bread and it would have given them a bit more coin to buy items like imported iron tools or fine cloth. But it also meant visits from government inspectors who regularly checked the weights, monitored the millstones, and collected the Republic's cut. Durss would have learned early on that the state was a constant, punitive force always watching over his family's livelihood.

A Region Under Watch

In 1525, the government outlawed all non‑Reformed religious practice and ordered the arrest of Anabaptist teachers and their followers who rejected infant baptism and state control over faith. Many were imprisoned, executed, or martyred. But by the 1600s, the Emmental—including the hills around Sumiswald—was fast becoming a covert stronghold for the Anabaptist movement.  Because Bernese authorities viewed this religious non-conformity as a direct threat to civil order, communities like Ober-Kneubühl lived under a cloud of growing political tension.
 
By 1610 the region was under the absolute authority of the Republic of Bern.  It strictly enforced adherence to the Swiss Reformed Church.  The lives of the local people revolved around the parish church of Sumiswald where births, marriages and deaths were meticulously recorded.  Much of the Aebi family history survives today because of these records.
 
Because a mill was a place where people constantly came and went it would have been the perfect place for traveling Anabaptist teachers or neighbors smuggling forbidden books and letters. Growing up in such a place, an impressionable young boy could easily gain exposure to radical, forbidden spiritual ideologies--right under the state inspectors’ noses!
 

Enduring Tragedy Together

While our story about Durss focuses on his affiliation with the Anabaptist movement, his life began in the Swiss Reformed Church with his parents and family.  The earliest traces of Ulrich Aebi and his family come directly from the official Sumiswald parish church books, proving they cooperated with the state church. It is not known why and how Durss and his family became Anabaptists, but his conversion must have been a defining event of his adult life rather than an inheritance from his father.
 
When Ulrich died in 1630 at the young age of 47 (his wife, Elsi, had died six years earlier at the age of 34), their children were left in a precarious legal position.  In Bern at this time, legal adulthood wasn't reached until age 21 or 25. At age 20, Durss was not yet legally an adult, and his younger siblings would have been assigned official state-appointed guardians. If they tried to divide or sell the mill, the state guardians would have taken a large portion, and the family would have lost their livelihood. To prevent the ruin of the family estate, the siblings had to stay together and run the mill. The brothers would have had to handle the heavy mechanics: hoisting 100-pound grain sacks, maintaining the water gates, sharpening (dressing) the heavy millstones, and managing the intake of grain from local farmers.  Running a mill also meant running a hospitality and bookkeeping business. Farmers often waited hours or days for their turn; they needed to be fed. The sisters would have had to manage the massive hearth, the large vegetable gardens, and the family's own livestock, while keeping the mill's ledger books balanced.
 
Seven months after his father’s death, Durss married Elsbeth Aeschlimann. Instead of establishing a new household, he brought Elsbeth into the mill, where she stepped into the role their mother had once held. Under Swiss custom, the siblings formed a legal property community, pooling the profits and living from the same kitchen. Since Ulrich and Elsi died young, the mill became the anchor that held the orphaned Aebi children together. Durss bringing his new bride Elsbeth into the mill in 1631 was the first step in stabilizing the family business, ensuring that the siblings could survive, work, and successfully launch their own adult lives from the safety of the family trade.

Convention Before Conviction

Records show that throughout the 1630s and early 1640s, Durss remained a fully participating member of the Swiss Reformed Church.  All four of his children--Andreas born in 1631, Elsbeth born in 1635, Anna Barbara born in 1641, and Maria born in 1643--were recorded into the parish church books at birth. In the early winter of 1645 Elsbeth died at the age of 32, leaving him to care for his children who were between the ages of 12 and 2.  He married Margret Steiner the following year. Nothing in his early adulthood suggests Durss’s conversion to the rebellious religious subversion that was to follow; everything points to a conventional, law‑abiding miller raising a young family. 
By the time the bailiff of Trachselwald Castle finally arrested Durss and his wife in October 1670, our 60-year-old grandfather had become more than just a quiet convert. The court documents specifically label him a töüfferischen ertzlehrer—an arch-teacher of the Anabaptists.  This would indicate that during the 1650s and 1660s, Durss had hosted secret meetings, preached, and solidified his role as a leader within the underground church network—likely using the traffic and privacy of his mill to coordinate the movement.
 
His arrest in 1670 was the moment that the Bernese government realized just how influential he had become. “For a long time, they had been looking for me and my wife Margret Steiner from Oberdiessbach,”said grandfather Durss, as recorded in the official court records of his interrogation. “Again and again we escaped the persecutors, often only at the very last moment. However, we were powerless against the extensive and systematic raids of the Anabaptist man-hunters paid by Bern in the summer of 1670.”
 
His eldest son, Andreas, tried to secure his release after they were taken into custody, but he was arrested as well. Eventually Durss, Andreas and 16 members of their family were stripped of their property and banished in November 1670, taking up residence in Helmstadt, Germany.
 
Recorded Durss before an official court interrogation, “For me, too, as a man, things went well for a
long time. Because when I was arrested for the first time in 1670 because of my Anabaptist convictions and imprisoned here in Trachselwald Castle, I was no longer the youngest at the age of 60. Over the years I was given more and more tasks in our Anabaptist community. At that time, many people in the Bern region longed for a better life, for more freedom and justice, for a dismantling of grievances in politics, society and the church. More and more sought and found answers to their questions in Anabaptist circles and joined our churches. Astonishing, actually! For especially since the Peasants' War of 1653, the persecution of our parishioners increased greatly. Nowhere was safe, anyone and everyone could be affected. This plunged many of us into hardship and misery. More and more I was consulted for difficult decisions, more and more despairing people I had to comfort, more and more sought pastoral counsel and biblical guidance from me. No wonder that the authorities became aware of me as an Anabaptist teacher.”
 
In the summer of 1671, Durss had returned to the Emmental to tend his congregation when he was caught by the authorities.  He was able to escape forced labor because he was 60 years old. Instead he was imprisoned in the Tittlinger Tower in Bern. Facing an indefinite sentence in the damp, freezing tower, he managed to break out. He resurfaced as a co-signer of a letter of thanks and supplication written by Anabaptist refugees from the Palatinate and Kraichgau to the Dutch Mennonites.  In 1679 he and Margret returned illegally to Switzerland, were captured, scourged[1], branded, and imprisoned again. Margret’s statement in the confiscation ledgers reveals the government’s motives:
 
My husband's first stay in the cold, damp dungeon at Trachselwald Castle lasted only a few weeks. Then the bailiff had him transferred to Bern, where he was henceforth locked up in the orphanage.[2] At the same time, our son Andres was also transported to Bern: In the meantime it had been discovered that he and his wife were also Anabaptists. And very quickly, by the way, the authorities had also determined that my husband and I were by no means poor and that there was "something to get" from us. Our home on Ober-Kneubühl alone was valued at 3680 pounds and together with our other property our assets were estimated at 5000 pounds.” 

Escape, Return, and Relentless Persecution

Between 1670 and 1684, Durss and Margret were held in both the Tittlinger Tower and one of the many local orphanages in Trachselwald.  They were scourged[3], beaten, branded, and fed only bread and water but would not yield to the Bernese Authorities. They were expelled from Switzerland over and over with the warning they would be executed if they returned, and yet they always returned.


The two were picked up again in Bernbiet, imprisoned in Trachselwald Castle and probably brought to Bern in the winter of 1678/79. Again, Aebi refused to renounce his Anabaptist faith. Only because of his old age he was not flogged but merely expelled from the country with a severe warning. But in January 1680 it was brought to the attention of the Provincial Lords of Burdgorf that the Anabaptist Durss Aebi had again returned to the country without permission. 

“We have been content to ignore his behavior, and he has been privileged[4] when we convey our displeasure only by word of mouth.  In consideration of his advanced age we know that he simply does not know the menace he causes by his unauthorized return to our country.  If he is bound to this course and continues to return he will be beaten with a switch.  It is therefore ordered that he again be banished from the country.”

The bailiff recorded their statements and asked Bern for instructions on what to do with the two of them. After a flogging with rods and a small allowance granted from their own confiscated property, they agreed to leave the country and the two were deported again. But that was far from the end of the never-ending story.

Durss was arrested, punished and banished or escaped multiple times between 1680 and 1684—a remarkable feat given his age and the brutality of Bernese prisons.  As he became more lame and frail, he continued slipping past guard and reappearing in Sumiswald, “poisoning the minds of many households,” as the minister complained. At each arrest the Governor of Trachselwald pleaded with him to stop his foolishness, whereupon he would be whipped and taken, again, to the border with the warning that another return would result in another beating.  The patience of the Bernese authorities had been worn thin, yet the conviction of Grandfather Durss was unrelenting.  Records of Grandmother Margret disappear after she was reported as ill during her imprisonment in 1681 at the age of 71.  It is presumed that she died shortly thereafter.

The Final Disappearance

The last record of Durss appears in May 1684 when he was 74 years old: “The aged and lame Aebi from Emmental had escaped from the orphanage.”
 
After that, history falls silent. No one knows whether he died hidden in the Emmental, sheltered by his brethren, or managed to reach his children in Germany.  He simply vanishes—one last act of defiance from a man who refused to give up his faith or his calling from God.


[1] The Waisenhaus orphanage, the city-state of Bern used in the 17th century not only for parentless children, but as a forced labor and penal facility for political and religious dissidents.

[2] Scourged: Flog or whip; to inflict punishment on (as by whipping).

[3] In this specific context, "privileged" means granted special leniency, favored, or treated with exceptional mercy. The authorities are stating that he was "privileged" because, up to that point, they chose to give him only a verbal warning ("our displeasure only by word of mouth") instead of the severe physical punishments—such as execution, hard labor in the galleys, or public floggings—typically handed down to returning Anabaptist exiles.

What Is an Anabaptist? And Why Were They Hunted?

If you’ve ever heard of Mennonites or Amish, then you’ve already brushed up against the world of the Anabaptists. These groups are part of the same spiritual family tree. But the story begins long before horse‑drawn buggies or plain clothing. It starts in the 1500s, in Switzerland and southern Germany, during a time when the government controlled every part of religious life. 
 

What Anabaptists Believed

The word Anabaptist means “re‑baptizer.” They believed:

  • Faith should be a personal choice, not something done to a baby.
  • The church should be separate from the government.
  • People should live peacefully and refuse violence.
  • No one should be forced to follow a religion.

These ideas sound ordinary today. But in the 1500s and 1600s, they were considered dangerous—almost revolutionary.

Why the Government Saw Them as a Threat

 
In Switzerland, the government and the church were tightly connected. Every birth, marriage, and death was recorded by the state church. Taxes were tied to church membership. Obedience to the church meant obedience to the government.

So when Anabaptists refused infant baptism, they weren’t just disagreeing about religion. They were rejecting the government’s authority over their families

The Anabaptist Hunt

Because of this, the government created a special task force called the Anabaptist Commission. Its job was simple:

  • Track down Anabaptists
  • Arrest them
  • Force them to recant
  • Confiscate their property
  • Or expel them from Switzerland

This period is often called the Anabaptist Hunt, and it lasted for generations. People were:

  • imprisoned
  • beaten
  • branded
  • starved
  • whipped
  • and even sent to row on warships (a punishment that was essentially a slow death)

Women were sometimes left alone if they stayed quiet, but once the government realized a family had money or influence, they were hunted relentlessly.

Where Mennonites and Amish Fit In

The Anabaptists eventually split into several groups. Two of the most well‑known today are:

  • Mennonites — named after Menno Simons, a Dutch Anabaptist leader
  • Amish — a later group that broke away from the Mennonites in the late 1600s

Both groups share the same roots as Durss Aebi. They carried forward the beliefs in peace, simplicity, and voluntary faith.

A Door Opens: William Penn and America

By the late 1600s, Anabaptists across Switzerland and Germany were exhausted from generations of persecution. Many had already fled to the German Palatinate, where life was safer but still unstable.

Then something remarkable happened.

In 1681, William Penn, an Englishman who believed strongly in religious freedom, founded the colony of Pennsylvania. Penn invited persecuted Christians from across Europe to settle there—especially groups known for peaceful living and hard work.

Mennonites and other Swiss Brethren saw their chance.

Beginning in the early 1700s, thousands of Anabaptists left Switzerland and Germany and sailed to America. They settled in Pennsylvania, where Penn promised:

  • freedom of worship
  • no forced tithes
  • no state church
  • and land they could own outright

For the first time in generations, they could raise families without fear of arrest.

Many of our own ancestors—including the Aebi/Eby line—eventually followed this path. Their story begins in the Swiss hills, passes through persecution and exile, and finally finds peace in America.

Why This Matters for Durss Aebi’s Story

Understanding the Anabaptist Hunt helps explain why Durss Aebi’s life was so extraordinary. He wasn’t just a man with unusual beliefs. He was part of a movement the government was determined to erase. Every time he preached, hosted a meeting, or simply refused to baptize a baby, he risked imprisonment, torture, or death.

And yet he kept going.

That’s what makes him one of the most remarkable figures in our family’s history.
