Dear friends at GS.....I cant believe it has been almost a year since I was on here!! Anyway, I have a question for you all related to DNA.... I have found that the tool on ancestry.com called ThruLines which I am sure you are all very familiar with, is very useful. If someone has a DNA match to you, it is virtually certain that they are related to you. Sometimes there can be a generation out but the match is conclusive. Not being an expert on how DNA works and how DNA matches work, I am curious as to whether any of you have found that there are people in your tree that you know you are related to, by blood line, but do not show up as DNA matches? Even more curious is a couple of times I have come across people I have a DNA link with, but whose cousins do NOT show up as matches to me!....any ideas anyone? Either there is some sort of logical explanation OR there were some strange goings on, back whenever!!...I would love to hear from anyone who has any ideas!! Best to you all, George (still in Vero Beach, FL)!
