hi there. my great-great-great grandfather Andrew Dunlevie (born about 1826 Ballimote county Sligo) moved from Ireland to Australia with his wife Margaret. It was here that the spelling of the last name was changed. I am replying to you as i found that Francis is a common family name in my family and has been for generations. Andrew and Margaret's third child was a boy named Francis Andrew Dunlevie born in 1851.
