Welcome to the Dillman DNA Project. This project was started in October 2002 and is hosted by the Dillman Family Association (DFA). The DDNA Project continues to grow in membership and importance to all Dillman researchers. As of May 2026 the DDNA currently has 52 members, two of which have tested mtDNA, and 16 distinct Dillman family lines.
FamilyTreeDNA supports international researchers — their website is available in multiple languages.
Project Objectives:
- To assist in identifying the origins of all Dillman families worldwide.
- To sort out the various Dillmans who emigrated to North America, Latin America, South America, Australasia and elsewhere.
- To scientifically validate and complement written documentation about the Dillman families.
- To make effective use of leading edge genealogical tools.
Project Benefits:
- Ability to compare your test results with those of other participants.
- Access to the Project’s high quality analysis and interpretation of results.
- Build possible bridges to gaps in documentation, brick walls.
- Challenge poor documentation corroborate existing documentation.
- Give an opportunity to discover relatives and families who would like to share their genealogical research.
- Provide an opportunity to participate in leading edge research while enjoying a group discount through FamilyTreeDNA.
Dillman DNA Project Requirements:
- Become a member of the Dillman Family Association. Contact the Dillman DNA Project administrator for a link which will give you a discounted price through FamilyTreeDNA.
- Sign the Release form provided by FamilyTreeDNA.
- For our web page submit a list of known ancestors in the direct male Dillman (or variant spelling) surname line and spouse with dates and locations of birth, deaths, and marriages. Having only a few generations should not discourage you from investigating and joining the Dillman DNA Project.
The privacy of participants will be protected by the administrator in addition to all members. Participants will only be referred to by their DNA test kit number. As is standard practice, only information on ancestors who were born prior to 1910 will be posted on the web site.
The National Geographic Society’s Genographic Project — a landmark five-year effort to map humanity’s genetic journey — concluded in 2019. Launched in partnership with IBM and geneticist Spencer Wells, the project completed over 40,000 kits and contributed significantly to the field of genetic genealogy. The Dillman DNA Project was proud to have members participate in this initiative.
