She was educated at various schools in Dublin, and studied Latin and Irish in University College Dublin (UCD). While there in 1931, she gave an address on "Women in Irish life long ago" which Philip O'Leary described in 2004 as "unapologetically feminist". She worked as a teacher before completing a masters in Old Irish.
