Thank you Trish, some fantastic info to look over. My James emigrated to Aus in 1857 (not convicts) and his daughter Mary Ann was born in Norfolk in 1853 and came over as a child. His wife was Maria Clarke (married 1852).
Looks like his mother, Annie, is complicated. I'm away for 10 days but when I return I'll try to weave this lot together!
