A friend of mine is seeking information on when her ancestors came to the United States. Her Great Grandmother, Josephine L. O'Donnel b. 1870, d. 1933 in Detroit, Michigan, married to John J. Stafford b.1866, d.in Detroit October 12,1933. Josephine's parents were John O'Donnell, b.1828, Abbeyfeale, Limerick, Ireland, d.1888 in Greenfield, Michigan. Josephine's mother, Elizabeth O'Donnell, b.1825 in Rockhill, Limerick, Ireland, d.1898 in Detroit, Michigan.
She is at an impasse to find when they came from Ireland, what was the departure port in Ireland, as well as where and when they arrived in the USA.
Does anyone have any idea when this might have taken place?
