My Unlce has vey limited information as he was only 2 when his father and mother seperated. He has not seen or heard anything of his father since then. Unfortunately allhe has is his birth certificate stating his fathers name and that he knows that he was born in Vancouver, most of the people that would have had any contact with him has since passed on.
We are unsure if he returned to Canada or is still in Australia, I have posted this message on the Australian, Canada, Burdette & Burdett gynealogy forum as a start. I am going to try to get the contact details for Birth Deaths and Marriages registry in Canada to try and obtain any information and also the Australian Registry.
My uncles wife has started to contact some of the Burdettes in the Canadian phone book, she was wondering if it were possible to speak to you over the phone. I can be contacted by my personal email@example.com if you would like to give us your contact details and a suitable time, as they may be able to give you something a little more which may have some more significance.
