Thrulines are based on yours and other peoples trees, but they only link you to people you share DNA with. I have one which turned up an incorrect father for my 3 x great grandmother. But with a bit of research I discovered the man was her older brother not her father. I was still related to the person Thrulines linked me to but in a slightly different way.
Another thing Thrulines picked up was two different relationships to the same person. I already had him on my tree as a half 3C twice removed - common ancestor was my 2 x great grandfather, but Thrulines found he was also my half 6th cousin from my 2 x great grandmother's side.
Though I don't think that's very surprising when there must have been a lot of distant cousins (who didn't realise they were) marrying in small rural villages. Impressed Thrulines found the 2nd relationship, I'm sure I wouldn't have made the link.
