Hello,
Glad to be on Ancestry. I'm wondering how accurate are some of the very long lineage's. On a few lines of my family, there is information (little green leaf pops up) from other ancestry trees going all the way back to 1000 a.d. in Wales. Once I started these long lines, each generation leads to another one very quickly. I guess people have done a lot of leg work?

Thanks,
Demian
