Celebrating a Former DNA Blogger
CeCe MooreI learned so much from CeCe Moore through her blog, presentations, correspondence, and many one-on-one conversations. After doing a video about my success story, she spent years helping adoptees find birth families.
She founded the DNA Detectives Facebook group and served with me on the Advisory Board of DNA Quest.
Now she is the leader in the field of Investigative Genetic Genealogy, using the methods she pioneered for adoptees to identify the perpetrators of unsolved crimes.
This article about CeCe and her work appeared in The New Yorker.
