I have created a Family Mystery Free Space Page for Bridget Byrnes (c1810-1880) Byrnes-1053 and William Twist (b c 1805) Twist-305, my great, great grandparents:
Space:Byrne/s_-_Twist_Family_Mysteries
They were married 18 March 1850 at Liverpool, New South Wales, while their daughter, Marian Twist-304 was born there on 26 December 1846.
Research indicates that William was a convict. I have been unable to find his death. Bridget may also have been a convict, but it's possible she came free, or even was born in the Colony. I have not found conclusive evidence.
Any assistance or comments would be appreciated.
Many thanks, Doreen
