"Family Finder' is the name one of the DNA companies use and I was being careless in using that term. There are three types of DNA tests used in genealogy. The first was probably Y-DNA, which is passed from father to son with little or no changes for many generations. My wife's cousin was a prefect match for a very distant cousin whose closest common ancestor was 14 generations back. It's very useful for surname studies because it traces the male line. The second was mitochondrial DNA (mtDNA), which is passed from mother to her male and female children, but the males do not pass it on. It traces the female line, but without the tradition of passing surnames on the female line it's harder to identify prospective matches, so it is less used. More recently autosomal DNA (family finder) has come into use. It looks for segments of DNA that are passed more or less randomly by males and females to their children. Because it is passed more or less randomly siblings or cousins will not generally have the same exact match, so you look for short segments that do match between subjects. Because it gets split more ways with each generation it only works very well for only a few generations, but it works for both male and female lines. It can be used to help verify suspected relatives. But mainly it is used by the testing companies maintaining databases of test subjects and looking for matches. If a person and an unknown relative both are tested they would learn from the DNA company of their match, and the probable distance of their relationship (cousins, second cousin, etc.). Like all DNA matches they would then need to use conventional research to figure out the actual common ancestors. Terry Reigel
Hi Betty, There are many descendants of John "Jack" Gann who have tested their autosomal DNA. You would likely have many matches on your Gann line if you decide to test.
