First find John MORRISSEY (b.1817) in marriage records of Dunhill and Fenor parish.
Feb 7,1837 John marries Catherine POWER. Four children are also mentioned in Baptisms in this parish,
Bridgit 1840-Catherine 1845-Joanne 1847-Margaret 1849
It is my believe that this family shows up in 1851 County Durham England census as the John Marres family.
I am looking to find any earlier information on this family in County Waterford. Some of the daughters in later England census' have claimed "Ballyduff " as birth place.
