My great-grandfather Patrick Harrington was born in Lowpark (Mayo) near Charlestown and baptized in Kilbeagh Parish on 17 Dec 1864. He was the son of James Harrington, who died circa 1878, and Margaret McDermott. Margaret may have been from Lurga Lower. I know many of her siblings' names.
An older brother of Patrick, John Harrington, stayed in Ireland. The rest of the siblings Maria, James, Catherine, William came to the USA with their mother and Patrick and settled in Chicago before the 1880 U.S. census.
I am looking for Harrington or McDermott relatives and more information especially about James' and Margaret's parents. I am planning a trip to Ireland next March.
