Born in 1933 to Albert Beale and his girlfriend Lou, she was adopted out to an Irish family. Pauline Fowler tracked Maggie down in 1997 and visited her and her family in Ireland. Maggie said how she was adopted to a family as her mum Lou had her while unmarried. Maggie had found her birth certificate which showed that Albert Beale was indeed her father and she was a full sister to Pauline, meaning Lou was seeing Albert for a few years before they actually married. Pauline said to Maggie that she saw her dad in her. While staying with the Flaherty's Maggie's lecherous husband Sean Flaherty flirted with Pauline and was abusive towards their granddaughter Mary Flaherty. When Pauline and her family leave, taking Mary with them, she begs Maggie to leave Sean and return to Walford with her, but Maggie decides to stay and look after her vast family. This is the last time she is seen.
