Your information sounds close, except for some of the dates, but I'm seriously willing to explore this further. James HEALEY (1830-1877)(died of TB; wife: Ellen SULLIVAN) came from Cork and landed in Eastport, ME (likely Boston). He worked as a Founder and became a citizen in Lawrence, MA in October of 1868 along with another James HEALY of Galway. His father was Dennis HEALEY; he may have been in Lawrence around 1874/75. I do not know who James' siblings were; I know he had at least one brother. James' children were: John, James, Mary, Julia-Theresa, Dennis (died age 1), and Catherine (died age 1).
