I think most of us know Edison Williams primarily for his involvement in this G2G forum, where he's a one-of-a-kind contributor. He is one of kind for sharing his expert knowledge of genealogical DNA in this public forum, where he provides well-informed and authoritative answers to questions about diverse DNA-related topics for the benefit of members who may have had no idea of the wonderful complexity of the topics they inquired about. I see this as a one-of-a-kind contribution, because I don't believe anyone else with his depth of knowledge would have the patience to bother to try to explain these things to the rest of us. I think we are all richer for his willingness to try. I have learned a lot from Edison's DNA posts here.
Edison also is a solid genealogist who is committed to high quality in genealogy, particularly in the use of evidence, and he reminds us of that periodically here in G2G, as in his recent comment in this recent thread about "secondary sources." I was a lucky beneficiary of his commitment to quality source citations when I was the winner of an Elizabeth Shown Mills book that he had donated as a prize for an early "Thon" event.
When I see Edison's signature on a G2G contribution, I make a point of reading what he had to say, because his contributions are always worthwhile (albeit long ).
Edison, please continue being the one-of-a-kind person you are, and a wonderful WikiTreer.
