Life

Saint Tysoi was a disciple of Saint Dubricius. The Book of Llandaff records the grant of Lann Tyssoi (now Llansoe or Llansoy in Monmouthshire) to the Church of Llandaff by Conhae, in the time of Bishop Berthwyn; the place is described as "the property of Saint Tisoi, pupil of Dubricius". He is probably the Soy who witnessed a grant to Llancarfan. The veneration is local, without synodal canonization.
