During the last year my parents (who are 3rd cousins) and I did the autosomal family finder test on FTDNA. One surprise was that a very good friend and neighbor with whom I thought I had no family relationship came up as a 5th or remote cousin on my test, with 116 Shared Cm and a longest block of 9. He did not show up on either of my parents' tests. Can someone explain why? I am not adopted, I show up as a daughter of each of my parents. Many thanks, Lynn Pollak Golumbic Haifa
