My father is also Craig Fothergill, he was born in Burnie, Tasmania, Australia.
His father was William (Bill Fothergill) he was born in England and migrated to Australia in the late 1930's. Rumour has it that he left a family in England and married my grandmother in Burnie although he was already married previously. I'm keen to find out more about that side of the family.
My father Craig has two brothers Nicohlas and Douglas (they are all in their 50's)and I have quite a few cousins here in Australia.
Good luck finding out more about your family origins.
