I'm tearing my hair out with posters on #Ancestry today.
Researching one particular family, this moning I've already discovered an uncle and his nephew whose lives have been incorrectly swapped, with the uncle's death now recorded at 117. And in another branch, a Reverend has been mistaken for a Sir in the family two centuries earlier, so that all later sons have been knighted as well. 😫
This is why I don't trust Ancestry trees!!
