Sybil Montagu, Prioress of Amesbury

Sybil Montagu or Montague or de Montague or Montacute was a daughter of John de Montagu, 1st Baron Montagu and his wife Margaret de Monthermer.^[1] At an unknown date she entered Amesbury Priory and became a nun, then in 1391 was elected the monastery's prioress. Her vigorous government led to a few stormy years in the monastery, in the period when the conflict between Richard II and his eventual successor Henry IV came to a head. She weathered that and later storms and died as prioress in 1420.
