Thanks for your posting. I am sorry, I do not have a birthdate for Stephen or Mary. I think that the John you are referring to must be the son of Luke not the father of Stephen and Luke as he was born in 1810 and they were married in 1802 and 1805.The John I am referring to wasfather of Stephen and Lukeand died in 1799. I don't know too much about Luke except that he was in the armoury and went to Mauritius where he died in 1821. John, Luke and Stephen were all gunmakers. I am only interested in direct descendants ( Stephen ) otherwise it gets too complicated and I do not have that much time. I wish that I could help you more.
