Margaret of Huntingdon, Duchess of Brittany
Margaret of Huntingdon (1145 – 1201) was a Scottish princess and Duchess of Brittany. She was the sister of Scottish kings Malcolm IV and William I, wife of Conan IV, Duke of Brittany, and the mother of Constance, Duchess of Brittany. Her second husband was Humphrey de Bohun, hereditary Constable of England. Following her second marriage, Margaret styled herself as the Countess of Hereford. Life. Margaret's parents were Henry of Scotland, Earl of Huntingdon and Northumbria, and Ada de Warenne. She has traditionally been considered the second-eldest daughter, younger than Ada, but it  is possible that Margaret was the eldest since she married before Ada and was named after their paternal great-grandmother Saint Margaret (while Ada was named after their maternal great-grandmother Adelaide of Vermandois). In 1160, Margaret became Duchess of Brittany and Countess of Richmond by marrying her first husband, Conan IV, Duke of Brittany, Earl of Richmond. Margaret's origins and first marriage were deduced by Benedict of Peterborough. Together Conan and Margaret had at least four children: Margaret's husband died in February 1171, leaving her a widow at the age of twenty-six. Shortly before Easter 1171 , she married her second husband, Humphrey III de Bohun, Hereditary Constable of England (c. 1155 – c. 1181). He was the son of Humphrey de Bohun and Margaret of Hereford. Hereafter, she styled herself Countess of Hereford. The marriage produced a son and a daughter: Margaret's second husband died in late 1181 and she then married the English nobleman Sir William fitz Patrick de Hertburn who acquired the lands of Washington in Durham in 1183. This marriage also produced three children: Margaret died in 1201 and was buried in Sawtry Abbey, Huntingdonshire. Her third and final husband had died around  1194. Portrayals in literature.
