Unfortunately, your dates and locations are only parallel to my dates and locations.
James HEALEY (1824-1877), son of Dennis HEALEY (1809-1875), was born in Cork, died in Lawrence, MA. He landed in Eastport, ME in 1846, worked in Boston until 1856 when he moved to Lawrence and married Ellen SULLIVAN. His children included James, John, Julia, Dennis (died in 1864 of unknown causes), Catherine. John and James were the only ones who lived long enough to marry. I'm still looking for siblings who died in the early 1860s.
