Owen Hearty was the father of Mary Hearty who traveled as a single woman on one of the “coffin ships” bringing Irish immigrants to New York in 1848. She married Swedish immigrant Eric Adolf Helsten in 1849. They lived in Haviland Hollow NY until they bought a tannery and moved to Gaylordsville CT. She received two letters from her father (1849, 1851), signed “your father Owen Hearty” and the return address said he was from Dorsey (letters mailed from the neighboring parish Newtownhamilton). Her marriage certificate says she was born in Dorsey Townland, Creggan Parish, County Armagh. Dorsey is located in the Barony of Upper Fews and Union of Castleblaney.
The above is what is known from information on "this side of the pond." What can be found in the Irish records about Mary's family? Some the following, I determined before my trip and confirmed when in Belfast.
