Elizabeth de Westcote

Elizabeth Littleton and Thomas Westcote had four sons. Thomas, the eldest son and heir, took his mother's surname, likely as a condition of her marriage settlement as heir to the manor of Frankley. Two of his brothers, Nicholas and Guy, retained the surname Westcote. Nicholas Westcote married Agnes Vernon, the daughter and heiress of Edmund Vernon, and was ancestor of the Westcotes of Staffordshire, while Guy Westcote married the daughter of one Greenevill of Gloucestershire, and was ancestor of the Westcotes of Devon and Somerset.[2]
