In page Margaret de Clare, Baroness Badlesmere:

"

Her father died on 29 August 1287, when Margaret was almost five months of age. His cause of death has not been ascertained by historians. Her mother married her second husband, Nicholas Avenel, sometime afterwards, but the exact date of this marriage is not known. Between 11 December 1291 and 16 February 1292, Margaret acquired another stepfather when her mother married her third husband, Adam de Cretynges.[citation needed]
