She was the seventh child of John Butler, gentleman farmer, and Ellen (née Forrestal).
She attended the Sisters of Mercy school in New Ross, County Wexford, entering the Congregation of the Sacred Heart of Mary in Béziers, France in 1876. She took the name Marie Joseph when she was sent to Porto, Portugal in 1879, professing in 1880. From 1880 to 1903 she taught in Porto and Braga, becoming superior of the school in 1893.[
