I am looking for information on the family of Martin Duffy (Duffey) and his wife Mary Byrnes. Their daughter, Delia, was my grandmother, who married Barnard Clancy in 1924. Other children included Norah, Ellen, Thomas, John, others? The children listed all emmigrated to the US: Norah 1910, Delia and Ellen 1920, Thomas 1925 and John 1928. Don't know if other children stayed in Ireland.
I beleive I found them in the 1901 Irish census in County Mayo, Barony Costello, Parish Annagh, Townland Knockanarra.
