Convicts10 on Family Tree Circles

I found out recently that my great great grandfather was a convict. He was transported in 1844, aged 22. His youngest daughter was born in 1875 and lived to 1972 - within my lifetime. I wish I'd known about this family connection, I would have tried to contact her. She was Amy Susannah Clark, later married I believe to a Mr Vernon Harcourt Johnson. I would be interested in finding any descendants who can tell me more about her life, and show me photos if they exist of some of those ancestors.
