Brigid O'Flynn was my great grandmother's name. She was Brigid Murry of the Isle of Mann Murrys, but she married Irish Catholic Jno O'Flynn and for all purposes was disowned by her family. She was said to be beautiful and from a very rich family, but her "mistake" ended with her moving to County Meath in Ireland where she had a daughter. Her daughter Rose Anne Brigid Flynn had her own misgivings about religion and was sent by her family to the United States as an indentured servant where she married Cornelius Hourihan ended in her being sent to New York as an indentured servant to a New York family. Her daughter Rose Anne Brigid. When I was a boy I was told by my father that the song was about his grandmother.
