History, Founders & Alumni


In 2012, a group of knowledgeable genealogists, citizen scientists, geneticists and IT professionals knew that advances in DNA technology could provide invaluable help to  those who were seeking unknown family members. This group of varying people helped to create what has become DNAAdoption and helped usher in the use of DNA for finding birth family.

One of the initial offshoots of this work was DNAGedcom.com which was started under the direction of Rob Warthen. This was the first system that allowed users to bring together lots of their DNA information quickly.  In fact, using this tool allowed Rob to find his wife’s birth father.

In 2013, this group realized there were not enough people who understood DNA well enough to help all those needing help.  The process of documenting all this information then began. Their plan was to take the combined knowledge of the group and provide a web site and training.

In 2015, DNAAdoption became an official 501(c)3 to ensure that its goal of educating and training the next generation of DNA Search Angels continued.  The folks below are not as active members of DNAAdoption as they were at one time, but we wanted to thank them for their hard work and dedication.


Co-Founders Emeritus

Rob Warthen – Co-Founder

Rob is the owner of and inspiration behind the tools at DNAGedcom and a co-founder of DNAAdoption and mitoYDNA. He got involved with DNA from his wife’s adopted mom who asked him to help his wife find her birth family.  Using only a few 4th cousin matches and his tools, he was one of the first to find birth family exclusively using DNA.  He generously donates DNAGedcom accounts to classes and provides tech support to our websites. He created a document for those who struggle with the Journey and are impatient with the time it takes.
