Thanks mosiefish that must be him! I dont have that census
another piece of information is that:
the family was eventually split into two, half the children were brought up by their fathers parents in the catholic faith, Letitia stayed with her mother's parents and she was brought up protestant.
Also, some of the children's names she can remember are Kitty, Mary, Louise, William and Owen She thinks there were 7 in total and Letitia was neither the youngest or the eldest
