I have details of Anna Maria's death, age, etc., which I can give you. She was related to the Nicholas Dodd (Ormond Quay, Dubin), who married Amelia Balfe, sister of the composer, Michael William Balfe.
Anna Maria had a sister, Jane Mary, who became a nun.
If you want to contact me offline, at glryan (at) eircom (dot) net, I can share what I have, and perhaps you might have some Balfe information.
