Hello Sandra
The 1911 they have about 9 children. I've got that one and have had a bit of a look on the public trees I can find but there are a few private ones. I have messaged each owner and I'm hoping they see this message.
Due to dads age I understand his father would have passed by now but I'm hoping someone told someone somewhere.....
Dad (Jack WELTON) was born 1925. I have his birth certificate (father unknown) but dad said the whole family knew the guy, that's why nana moved to Australia after having him.
