Hi Peter, I too am trying to trace Fox's in Ireland, mine seem to be based around Killeigh in Offaly but i've come across many records with similar names from Dublin.
Christopher Fox BIRTH ABT 1806 • Killeigh, Offaly, Ireland DEATH unknown but 1847-1860 MARRIED 4th Nov 1836 in Philipstown to Margaret Byrne BIRTH abt 1806 • Ireland
DEATH 15 OCT 1881 • Keilor, Victoria, Australia.
They had 4 children that I am aware of, Bridget, Michael, Mary and Hanoria. Margaret was listed as a widow when she came to Australia with their son Michael who is my 3rd great grandfather. He married an Irish woman in Australia, Rose Reilly from Westmeath/Meath. They settled around Keilor in Melbourne.
My family and I are visiting Ireland in September this year :)
