Honoring the Forgotten: Completing 442 Purple Triangle Profiles on WikiTree

Three days ago, on August 28, 2025, I reached a milestone that has been months in the making. Profiles for all 442 Bibelforscher documented in the Ancestry.com Dachau concentration camp records has been created. Each profile represents not just a name and date, but a person who suffered persecution for their religious beliefs during one of history's darkest chapters.

Update: Joined the WikiTree Saturday Roundup and spoke about this milestone!



The Purple Triangle Badge

Most people recognize the yellow Star of David or the pink triangle, but fewer know about the purple triangle. This was the badge Bibelforscher—members of the Bible Student movement and Jehovah's Witnesses—wore in concentration camps. These individuals were imprisoned not for their ethnicity or political activities, but for refusing to renounce their faith and pledge allegiance to the Nazi state.

Why This Project Matters

When I started the Purple Triangles - Dachau project on WikiTree, I was struck by how little attention this group of Nazi victims receives in mainstream Holocaust education. These 442 individuals represent just a small section of the Bibelforscher at different camps, and even at Dachau itself. They were simply the most easily identifiable group within the Germany, Dachau Concentration Camp Records, 1945 record set on Ancestry.com. These 442 individuals deserved to have their stories told, their names preserved, and their descendants given the chance to discover their family history.

WikiTree, with its mission to create "a global family tree for our cousins and descendants to enjoy for free, forever," provides the perfect platform for this type of memorial project. With over 42 million profiles and more than 1.2 million community members, it's become the most trusted collaborative family tree—and it's completely free.

The Research Process

Creating these profiles required more than just copying names from records. Each entry involved:

  • Cross-referencing multiple sources: The Ancestry.com Dachau records served as my starting source, but I verified information against the Arolsen Archives (formerly the International Tracing Service). There were some transcription errors between Ancestry and the actual document on Arolsen.
  • Contextual research: Understanding the historical context of Bibelforscher persecution
  • Careful documentation: Ensuring each profile met WikiTree's standards for sourcing and accuracy
  • Respectful presentation: Balancing historical accuracy with dignity for the victims and consideration for any living descendants

The Arolsen Archives proved invaluable as a primary source. As the world's largest archive on the victims and survivors of National Socialism, it provided additional details and verification that strengthened the reliability of each profile. 

The Human Stories Behind the Numbers

While working on this project, it became impossible to see these as just "442 profiles." Each name represented someone's father, mother, sibling, or child. Someone who chose their faith over their freedom, and in 167 cases, ultimately paid the highest price.

The age ranges surprised me—from young adults barely out of their teens to elderly individuals who had lived full lives before their world was turned upside down. 

What's Next

Completing the Dachau records is just the beginning. The Purple Triangles project includes other camps and locations where Bibelforscher were imprisoned. There are thousands more stories waiting to be told.

These profiles also need to have their family members added and to be connected to the main tree. Can you help us get them connected?

Why WikiTree?

This project reinforces why I believe in WikiTree's mission. Unlike commercial genealogy sites that lock family history behind paywalls, WikiTree ensures that these important historical records remain accessible to everyone. Family historians, researchers, students, and descendants can access this information without barriers.

In a world where Holocaust denial persists and historical memory faces constant threats, projects like this serve as digital monuments. They ensure that the names, stories, and sacrifices of persecution victims are preserved for future generations.


The Purple Triangles - Dachau project continues to accept contributions and welcomes anyone interested in Holocaust research or family history preservation. Visit WikiTree to learn more about contributing to our collaborative global family tree.

Connecting profiles to the free global tree on WikiTree

This weekend is one of four annual marathons on WikiTree. Today, as part of this project and this marathon, Connect-a-Thon XIII, I'll be working to connect previously added profiles to the global family tree. 

Last week adding the maintenance category of: Jehovah's Witnesses, Family Tree Size One was discussed and shown. This week we'll be picking profiles from this category and trying to get them connected. Let's get the family members of these ancestors added and see if some of them may already exist on WikiTree!

Today I'll be working on Leopold Engleitner who was an Austrian conscientious objector and a survivor of three concentration camps; Buchenwald, Niederhagen, and Ravensbrück. You can read more about him on his profile and Wikipedia page.

We'll start by adding his parents; Leopold Engleitner and Juliana Haas and his siblings; Heinrich, Wolfgang, and an unnamed brother who died in infancy.


As mentioned during the tutorial, here are links for some recommended Chrome Extensions:

Building the Purple Triangles Dachau Memorial Database: Progress Update & Tutorial

In our ongoing mission to document and honor those bibleforscher connected to Dachau, we continue to make steady progress. Last week marked an important milestone as we introduced the project and shared a supplemental free-space page, along with an example profile. We successfully completed all profiles for surnames beginning with 'D' last Sunday.

Today, I'll guide you through the process of adding new profiles using the record collection for Dachau on Ancestry.com as our primary source. I'll demonstrate this with a step-by-step example record to help fellow researchers contribute to this important work. We currently have 10 entries pending for surnames beginning with 'E', which we aim to complete today.


One of our key objectives is fostering collaboration across the genealogical community. By sharing our research across different genealogy platforms, we create opportunities for researchers to connect, verify information, and expand our collective knowledge of these historical records.

In the video above you can see the different repositories used for providing source documentation for these profiles and the source citation for each. 

As mentioned during the tutorial, here are links for some recommended Chrome Extensions:

We've now documented 92 individuals out of 435 in the Dachau records collection. Here are today's ten completed profiles:

The Purple Triangles sub-project on WikiTree

WikiTree is a free genealogy website, where genealogists collaborate on a single family tree. Back in 2015, the Holocaust Project was created, and the Religion sub-project, Jehovah's Witnesses was started in 2019.

Purple Triangles is a part of both of these projects, as Jehovah's Witnesses that were persecuted during the Nazi regime were identified with this symbol. The focus of this project is to document and memorialize victims of religious persecution, and connect them to the global tree.

An estimated 10k Witnesses were imprisoned between 1933-1945, about 2k Jehovah's Witnesses died during the holocaust, an estimated 400 were executed, over 1k died in concentration camps, some were killed in gas chambers, medical experiments or lethal injections.<Currently, the focus is working on the Dachau collection available on Ancestry.com, as there is an indicator for whether the victim is a "bibelforscher" or Jehovah's Witness, of which there seem to be about 450. See the space page: Purple Triangles - Dachau

WikiTree functionality allows grouping of profiles into categories, like "Dachau Concentration Camp Prisoners". This functionality will also be used for maintenance of these profiles, for example, "Jehovah's Witnesses, Family Tree Size One", indicates that family members need to be added to the grouped profiles. Members can then pick from that category when they are working on challenges such as the upcoming Connect-a-Thon, where the focus is adding as many profiles as possible during a weekend.

Each Sunday this blog post will be updated with the status of this project along with the list of profiles added that week.
