I got this from a researcher. I do not know if it is the correct family.
Donegan/Donigan/Doonegan Newtownforbes, Longford Co. Kilmore Townland, Carrickmoyah. Parents: Patrick Donegan/Rose Dowd. Children: Catherine(Kate) Dec. 19, 1890 sponsors: Thomas Barden/Brigid Donegan Patrick Dec. 23, 1988 sponsors: John Donegan/Catherine Mullooly. Twins Brigid and James Jan. 2 1894 sponsors: John Kelly/Brigid Donegan. There may have been more children.
I know Kate came to the USA and then went back to Ireland on the steamer St. Luie an American Line about 1915, because of her parents illness/death. She had brother/brothers that were going to California, do not know if they made it.
