The information I have is Catherine Sarsfield came to Australia in 1880 and married Patrick Joseph Murphy in 1886. Their children were Margaret Mary (May) b.1888 married Fitz-walter, James (Jim) Joseph Sarsfield Murphy b.1890 and killed in the war, didn't marry, Eileen Gertrude b.1892, didn't marry, Thomas (Tom) Sarsfield Murphy b.1894, I don't know who he married, but had a daughter, Winifred Maud b.1897 and married Leach, and Kathleen Agnes B.1904 and I don't know if she married. I remember visiting Eileen and Kath Murphy when I was little. Catherine Sarsfield was born about 8 years after Winifred Sarsfield my great-grandmother who had Mary Hyland as her mother in her Wedding Certificate. In that 8 years, Mary Hyland may have died and Michael Sarsfield may have re-married. That might account for Catherine having a different mother. What do you think?
