Jeremiah Donohue (O'Donohue, O'Donoghue, Donohue) in my family tree. Born abt 1837 in Ireland, married to Hannah Connors (Connor, Connors, O'Connor), born abt 1849. Lived in Manhatten & Brooklyn. Children of Jeremiah & Hannah (as per my mother's recollections) were were Julia & Hannah. My research indicates there may have been more to include: Mary, Kate, and James. The Hannahs also seem to be known as Anna or Annie. I have seen your specific "Donahue" spelling, but I assume it is just another possible variation. Any connections out there?
