In or shortly before 1200, Maud married her first husband Theobald Walter, 1st Baron Butler (died February 1206), son of Hervey Walter and Maud de Valoignes, and went to live in Ireland. His brother Hubert Walter was Archbishop of Canterbury. In 1185, Theobald had been granted land by Prince John, who was then Lord of Ireland. He was appointed Butler of Ireland in 1192,[citation needed] and High Sheriff of Lancashire in 1194.
