William DE LANCASTER

  General Notes:

https://en.wikipedia.org/wiki/William_de_Lancaster_I
William de Lancaster I, or William Fitz Gilbert, was a nobleman of the 12th century in Northwest England. According to a document some generations later, he was also referred to as William de Tailboys (de Taillebois) when younger, and then became "William de Lancaster, baron of Kendal", although there is some uncertainty amongst most commentators concerning the exact meaning of the term "baron" in this case. He is the first person of whom there is any record to bear the name of Lancaster and pass it on to his descendants as a family name. He died in about 1170.

William married Gundred DE WARENNE, daughter of William DE WARENNE , 2nd Earl of Surrey and Unknown.
