Maud of Lancaster

Maud of Lancaster (c. 1310–1377) was a daughter of Henry, 3rd Earl of Lancaster, and Maud Chaworth. In 1327 she married William de Burgh, Earl of Ulster, and lived in Ireland, where their daughter Elizabeth was born. After William was murdered near Carrickfergus in 1333, she fled with her daughter to Edward III's court.

Her second husband, Ralph de Ufford, was Justiciar of Ireland until his death in 1346. Widowed again, she became a canoness at Campsey Priory, later a Poor Clare at Bruisyard Abbey, where she died in 1377.
