I reread your posting and learned you are looking for a Jeremiah Donegan whose parents were James and Margaret. Do you know where they lived in NJ? The Donegan relatives of my husband first came to Jersey City in the 1880-90's. My husband's grandmother Elizabeth Donegan was born in Edenderry, County Offaly. Her father, John Donegan, was born in County Laois and her mother was a Walsh form County Kildare.
