First do you know anything about Ann Mason, where she was from, who her parents/sibblings were.? I know of a Eliza Mason born in Oklahmoma and married Patrick O'Donnell from Co Cork.Patrick's parents were John O'Donnell and Elizabeth Carney. He had two brothers I know of Peter(older) and John F who married Bridget Doherty also of Co Cork. Her parents were Neil Doherty and Mary Coats.
I also have another Patrick O'Donnell my grandmothers oldest brother born in Co Donegal 1867. and have no information on him---yet----someday maybe ---i hope. His sibblings were: John 1868, Neil 1871, Mary Ann*1873, Maggie 1875,Denis 1878, and Philip 1880. All but Patarick and Maggie as best I can tell immigrated to MA.
