Thanks for your reply Sue. I was looking for the parents, particularly the mothers' maiden name of two families, using the youngest children, who would fall into civil registration:

Philip S. Moore born 1880 Patrick, s/o of Margaret J ? & ? (father away fishing at 1881 census)

This one was actually born in Lonan, but he's not in Brian's list either:

Frederick S. Moore born 1900 s/o Robert S Moore & Isabella ? (possibly Kissack) (1901 census)

I was separating this Robert Stephen Moore from the one who was connected to my tree and wanted to tie up the loose ends.
