I don’t know if I’m just doing something wrong but I built my family tree and the website seems to have barely any information about my family at all. I found out more just checking out our national archives then what I found on this website. It’s maybe worth noting that I’m not in the US and it does appear to be somewhat US-centric.
The best it could find was a couple of enrollment records for voting and a single immigrant notification in an old newspaper. It didn’t find these either by itself, I had to manually go though the search system to find it. The OCR didn’t even get the spelling of the name correct.
I’m not sure what I expected but it was definitely better than this, especially for all the pay walls they throw up.
You just have to keep giving them more and more private information about yourself and your unwitting family, then something magic happens.
