Hi,
Had the same thing happen to me. Everything fit like a glove. Even found some descendants of the person- Stanley -who had been the only one listed in that year!!
Then I received copy of a letter which had gone to various people from a lawyer in UK-basically stating that children of particular people would share in a will. And this family weren't there (and they were UK based).
So started digging around and decided that it would be worth revisiting all of my work around this family and in particular this individual.
I knew that the parents had given the eldest child exactly the same names as the mother (all 4 names) so wondered if Stanley was also given all of the fathers names-3 of them and if Stanley was a second or third name. I knew the mother called herself by one of her other names so wondered if Stanley was called that to stop confusion with his father William.
Found an birth index one with 3 initials and when I mentioned the error I had made to a relative in the UK he, unbeknowst to me, brought the certificate- and sure enough Stanley was in fact William Stanley S even though on all census, people's memories of what relatives had said, etc he was Stanley.
Have kept the information on the 'other' Stanley as I had gathered quite a lot and am passing it on. Have taken it all off the database.
One good thing though is that an older gentleman that we thought was related is not upset as it has given him, so he says, the impetus to go looking for more of his rellies and to write down his side of the family history for his grandchildren.
However this is something that can happen to anyone in good faith.So my "somebody/somewhere" time has come.
My motto now is to double check the double checking!!!!
