Relying on Ancestry to go back much beyond the mid to late 18th century is fraught with problems. There's just so much info that is sourced solely from "Ancestry Trees" but all that means is someone else has made the connection with no guarantee that they are right. Others then see the connection and copy it to their trees and so on until the link acquires a life of its own. The census returns from 1841 permit cross checking to help make sure links are right but before then, it is very easy to get it wrong, especially when villages often contained extended related families that had two or more couples with the same names.
My 3 x great grandfather's grave is three miles away from me in the village where he died; every other person researching him has him dying 200 miles away because that's the first record that comes up on searching for someone of his name and age. His mother's maiden name is incorrect on most Ancestry trees as well because they've chosen someone local with a similar forename and age without knowing that her maiden name is given in the original records in the record office.That is really the Ancestry problem because one error renders everything earlier for that line completely wrong.
I used to message people when it was obvious they had got things screwed up but gave up as there was just too much that was out. I did change my mind when I found one Canadian family had made a pilgrimage to East Anglia, with more family members to follow, to see one of their ancestor's home areas when in fact the person concerned grew up near Reading, where she married. This was down to two people with the same name, birth year and parents names, one in Essex and one in the Reading village. Fortunately, copies of the actual baptism register were online to show who was who. The father of that person was a documented survivor of the Charge of the Light Brigade, so was much more interesting than my own ancestor!
