Edward James Hayden son of Edward Hayden and Margaret Merrigan was baptised in 1845 St Marys in Haddington Road RC so therefore you now need to widen your search estimate to cover 1845 ...no other children have I found to the parents. And nothing more on them either http://churchrecords.irishgenealogy.ie Merrigan is a co Wicklow Surname also if that is of interest to you as well. Cheers Cara
