How do i find out Mary Campbell shaws parentage?
Mary does not appear in the Tasmanian birth records or marriage records. Perhaps they married elsewhere and emigrated. The Tasmanian Archives website which states she was born 1843. The double barrel name could mean she was registered under either Shaw or Campbell. I have searched on familysearch.org but nothing. There is a submitted record [I always treat any family trees or submitted records online with a degree of caution] on family search for the birth of an Allen SMYTH with parents George and Ann BLACKMORE but if I remember it is in a different year to the info you placed on one of your other posts on rootschat.
I note you live in Tasmania, perhaps you could visit the Tasmanian Archives for more help.
Another chatter may have a suggestion or two how to help you.
Good luck with your search.
Cheers
