Welcome to the boards, Buckley85.
Rootschat does not let the names of living people be discussed on here, so it is going to be difficult identifying people.
Do you know who your Father's parents were, and if he had any siblings?
You do not mention your Mother - do you know about her side of the family?
Is your Father still alive (if so, please remove his date of birth), and which of your family live in Australia?
You mention unknown relatives - are these going to be people who are only remotely related to you?
Thank-you
