Dee Nairn,
Yes, John Deaves the convict was married to Susan Rayner (b.1786), before he was transported to Australia.
Harriet was also married to a Stephen Parker, with whom she had three children Elizabeth, David Edward and Sophia Jane.
Harriet and John's children we John William (1821-1888), William John (1824-1899), James (1827-1863), Ann Rebecca (1836-1911) and Charlotte Priscilla (1834-1868).
As you are descended from Ann Rebecca, I would be very interested to see your line from her to you. I can offer information on John Deaves the convicts family, and Harriet Pugh/Parker's parents, if you require this information.
Yours sincerely,
Luke
