The Jesuits bought Tullabeg in 1818 (dedicated it to St Stanislaus) and opened a preparatory school for boys destined to go to Clongowes Wood College, Kildare. St Stanislaus College gradually developed as an educational rival to its sister school. It merged with Clongowes Wood College in 1886. Tullabeg then became a house of Jesuit formation: novitiate (1888-1930), juniorate (1895-1911), tertianship (1911-1927) and philosophate (1930-1962). In 1962, it was decided that the students of philosophy should be sent abroad for study. Tullabeg subsequently became a retreat house and was closed in May 1991.
Sophie Stephens was daughter of Doctor Stephens and Sophie Hyland.
Matthew Stritch recieved his Bachelor's Degree in Medicine from Trinity College Dublin in the year 1793. He then married Sidney Craig, daughter of William Craig. They had a daughter named Maria Blanche Stritch around the year 1798.
