Hi!
I wasn’t sure how to word the question. My 2x great grandmother Mary Byers (née Burden, née Long) had a child three years after her first husband Thomas Burden died at Woodend, Victoria, in 1873. Frank Henry Burden was born at Woodend in 1876, so obviously can’t be Thomas’ child. She married Richard Byers in 1878, two years after Frank’s birth. I suspect but can’t prove that Frank is Richard’s son. How can I add him as a son of Mary, with an unknown father, when the only choices on the form are Thomas or Richard? As I said I know he can’t be Thomas’ and can’t prove he’s Richard’s.
