Gospatric, Lord of Workington in Coupland, exchanged his lands with his cousin, William I de Lancaster, Baron of Kendal. William was the son of Gilbert a Norman knight and his English wife, Goditha, daughter of Eldred the Thane, Lord of Workington. Goditha was the sister of Ketel, Baron of Kendal. The Barony of Kendal probably passed to William through his aunt Christina, wife of Ketel, 3rd Baron of Kendal. William and Goditha were the parents of a second William de Lancaster who married Gundred de Warren, widow of Roger de Beaumont, the 2nd Earl of Warwick. They also had a daughter named Avice who married Richard de Morville, Constable of Scotland.

I appears that William de Lancaster I had been in high favor with William, Count of Boulogne and Mortain, Earl of Warren and Lord of Lancaster, who acquired the Earldom of Warren by his marriage with Isabel, the only daughter and heiress of William, third Earl of Warren, and the Honor of Lancaster by confirmation of King, as his rightful inheritance. Earl William, or Henry II, married William de Lancaster to Gundreda, sister of William, third Earl of Warren and widow of Roger, Earl of Warwick. It appears that at the same time, William was enfeoffed of one knight's fee in Ulverston, Warton and Garstang, and important estate of thirty six and one-half carucates of land. It was doubtless that at this time he assumed the surname of Lancaster, with the licence of the his chief lord and the King.
