I realise that this is an old post but am hopefully you can still receive this because I am hoping that we have a connection.
my ancestor Mary Laphen was born Dublin circa 1856 and was living at 3 moore street when she married Joseph Jordan on 30 July 1871. Her father was John Laphen and her mother was Eustace (at least thats what the marriage entry looks like.)
Mary continue to live in Dublin and had 11 children , 10 surviving as at 1911 census.
the baptism record for the children suggest that other laphen family ( sponsers of Mary's children) include: Daniel Laphen Andrea laphen Anna Teresa Laffan Emilia M Laphan
the moore street connection would suggest that they are related in some way.
look forwards to hearing from you
