phoned my aunty and she confirmed that his fathers name was Samual, so as far as i'm concerned the birth cert is the correct one.
and then she said something which i thought was a little strange but just put it down to one of those stories that get pased down from generation to generation, she said '' it's not really Hendren you know, it's Henderson, they had to change for some reason, but we were never told why.''
those were her exact words spoken today(well yesterday as it's after midnight now) so it appears that perhaps williams children which included my mother never knew that there fathers sisters and brother were not blood related.
Although saying that, on william hendren's birth certificate, it has his mother as mary jane hendren, formerly Russell.
but for my aunty to mention about the name change, and then i come on the forum and find the info etc , very strange. any ideas of what my next step should be would be appreciated.
i will try to find out the date william died if i can.
many thanks to you all for all your help
