I am searching for the family of John Molloy who married Eliza Kerans 5 Jun 1850, Durrow, Kings County.  I have a letter that was written in 1861 by his father Charles Molloy that says John was living at the 'White Forge' with his family and at that time had 3 sons and one daughter.  He held 30 acres of land and was under agent to Lady Norberry.  I have located the birth of a later son, Samuel Robert who was born abt 1865.  Any help or suggestion on how to find further information on this family would be much appreciated.
Thanking you.
