Walk into a one-room schoolhouse in Lancaster County and you might find six kids named Stoltzfus in a class of twenty. That's not a coincidence — it's the direct result of a naming system built for stability, not variety. Amish communities draw given names almost entirely from the Old and New Testaments and surnames from a small, closed set of Pennsylvania Dutch and Swiss-German family names that arrived in North America two centuries ago. The pool hasn't grown much since. It's one of the few English-speaking naming traditions in the country where you can predict a person's community just from their last name.
A Given Name Pool That Doesn't Chase Trends
Amish given names skip whatever's trending at the county hospital's nursery. Biblical names dominate, and they've dominated for generations. Abner, Enos, Amos, and Levi for boys. Salome, Naomi, Anna, and Sarah for girls. These aren't retro picks revived for their vintage appeal — they never left.
Nicknames aren't a casual shortcut here — they're often the name someone answers to for life. Elizabeth becomes Lizzie on the birth record's second reading. Sarah becomes Sadie before she's out of diapers. Nobody in the community thinks of these as "short for" anything.
Three Settlements, Three Surname Clusters
Surnames tell you more about geography than genealogy. Move from Lancaster County to Holmes County and the last names change almost completely, even though the given-name pool barely shifts.
The oldest settlement, with the most concentrated surname pool
- Stoltzfus
- Beiler
- Esh
- King
The largest Amish population in the world, anchored by two names
- Miller
- Yoder
- Troyer
- Hershberger
Shares Miller and Yoder with Ohio, diverges after that
- Miller
- Yoder
- Bontrager
- Hochstetler
Notice Miller and Yoder show up twice. That's not overlap by accident — both settlements trace back to overlapping migration waves from Switzerland and the Palatinate, and the surnames simply traveled with the families. Lancaster split off earlier and kept its own cluster almost entirely separate.
When a Surname Stops Being Useful
Here's the problem a name pool this small eventually creates: once a surname covers a third of a church district, it stops doing its job. Directories can list two hundred Stoltzfus households in a single Lancaster settlement. So the community improvises.
- By teknonymy — "Sam's Katie" or "Dan's Amos," naming someone through their father or husband
- By nicknames attached to a surname — "Speck Stoltzfus" to separate one Stoltzfus line from another
- By occupation or farm location — "the harness-shop Millers"
- Inventing a new surname to stand out
- Adopting an English surname for variety
- Using a middle name as a everyday identifier the way English speakers do
Teknonymy is the real workaround, and it's older than the settlements themselves. It's a system that assumes everyone already knows the family — which, in a community this size, they usually do.
The Numbers Behind the Pattern
None of this is anecdotal. The concentration is measurable, and it's part of why genealogists find Amish records both easier and harder to work with than most American family trees.
A closed surname pool sounds like a limitation. Inside the community, it functions the opposite way — it's a signal of belonging, not a shortage of imagination.
Common Questions
Why do so many Amish people share the same last name?
Amish settlements descend from a small number of founding families who emigrated from Switzerland and the Palatinate region in the 1700s and 1800s. Because Amish communities are largely closed to outside marriage and new surnames rarely enter the pool, a handful of family names — Stoltzfus and Beiler in Lancaster County, Miller and Yoder in Ohio and Indiana — account for a disproportionate share of any settlement's population.
What is teknonymy and why do Amish communities use it?
Teknonymy is identifying a person by their relationship to a parent or spouse instead of by surname — "Sam's Katie" means Katie, daughter of Sam. It solves the problem a small surname pool creates: when a third of a church district shares one last name, the surname alone doesn't distinguish anyone. Teknonymy assumes shared community knowledge and works because everyone already knows the families involved.
Are Amish given names only from the Bible?
Mostly, but not exclusively. Old Testament names like Abner, Enos, and Levi dominate, alongside New Testament names like Aaron and Daniel spelled the biblical way. A smaller number of names, like Menno (after reformer Menno Simons), come from Anabaptist history rather than scripture directly. More assimilated New Order communities have also adopted a handful of plain, non-biblical English names — Wayne, Melvin, Marlin — though these remain far less common than the biblical core.
Do Amish surnames differ much between settlements?
Yes, noticeably. Lancaster County's surname cluster — Stoltzfus, Beiler, Esh, King — barely overlaps with Holmes County's Miller, Yoder, and Troyer, even though both settlements share the same given-name traditions and religious practices. Holmes County and the Elkhart-LaGrange settlement in Indiana overlap more, since both trace back to related 19th-century migration routes, sharing Miller and Yoder as anchor names before diverging into settlement-specific surnames like Hershberger in Ohio and Bontrager in Indiana.
