Her husband always suffered with ill health and died in 1890. Her only son, George Robert, died of
tuberculosis in 1894 after his mother took him to
Switzerland in an attempt to help him. Because the lands of her husband were entailed his nephew was the new heir to the estates and Taaffe was left homeless and with a limited income. Initially she moved into the Presentation convent in
Lucan but she had no intention of becoming a nun. She still had a certain income of her own and used it to move to Dublin. Having spent years involved in charity work, Taaffe focused on it now. From 1867 she had been a friend of Canon
Joseph Léon Roy. He had established an archconfraternity and shrine for St. Joseph at
Maranville,
France. After becoming a widow Taaffe became the administrator and secretary of the Irish branch. She mostly lived in Dublin after that. In 1895 she arranged for the publication of an Irish edition of the association's magazine and created what went on to become St Joseph's Young Priests Society. They educated young Irish men who wanted to become priests in Asia. Taaffe ensured support of the organisation with successful fund raising events. Her work in establishing the society with Fr Browne and Fr Darlington, the first editors of the magazine, were so successful that the organisation expanded from being able to fund the education of the original 2 men to 36 men by 1923 and had over 100,000 members by 1997 and funded 711 young men. Taaffe died on 3 May 1918. She is buried with her husband and son at the graveyard at St Catherine's church, Ballapousta, Ardee. ==References and sources==
