John Rousseau is a mystery man and I have only a limitted amount of information about him.
I am interested in finding out more about him as he was instrumental in my ancestors life. Rousseau was first married to Lucy Lane with whom he had 5 sons (THe last one was born and died soon afterwards in Sydney), however in reality 2 were very possibly not his. He also had another child with a previous de facto (convict). He died in 1812 in the Calcutta area, hung for murdering his second wife. There was one month between trial and execution.
I am from the Sharling line, what is your link to him?
I hope this helps.
