Hi Anna,
I'm Deirdre and have just been in contact with your friend, Mary, from Rathmore about the Grace-Fitzgerald connection. My grandfather was Gerald Grace, youngest son (7 siblings) of david Grace and Ellen Fitzgerald. I don't have much on the Fitzgeralds but I know that the 2nd youngest sibling was Richard (Dick) who became a teacher and moved to East Anglia. Just saw a Richard Fitzgerald living in Lisbealad on the 1901 census - 94 years old, "widower" and living with 3 young adult children of his. Could that be Ellen's father who married twice???
