I removed details of possible living people (yourself, your siblings, etc.) since Rootschat policy doesn't allow us to put on details of possible living people.
If you'd like to trace your father's family back then it should be fairly straightforward. I think Welsh marriage certificate list father's name and occupation- details you might not have yet.
Scottish certificate have much more detail than England or Welsh ones so if you get your father's birth certificate it should list the names of both parents as well as the date and place of their marriage.
