I find it very useful, saves me a lot of time figuring out how people connect. I have been working on making my ancestors genealogically defined. I don't think these lines are bogus. Most have vital statistics and are written up in family genealogies. I would like a way to put categories or stickers or tables...for Thrulines like there is for DNA Circles. I have started documenting them on my profile. Most of my ancestors up to 5-6 generations have thrulines, several 20 or more DNA cousins, This seems to add credence to the paper trail. In a way it surprises me that I haven't found surprises. There are a few adopted children that have found their way into the family through DNA, welcome aboard. It is nice when family is acknowledged!
