The death certificate of Michael Phelan, b. 1862, Ireland and died 1911 in Manhattan, NYC, lists William and Margaret as his parents. No specific place in Ireland is named for any of them.
Michael was in Philadelphia, PA as early as 1888, but there is no indication that his parents left Ireland. He moved to Manhattan about 1892.
Any clues as to where in Ireland this family lived would be greatly appreciated.
