Sir William de Hilton, Knt., of Swine and Winestead - Bequest to Sir William Hilton

"Sir William Hilton, he gave Swyne and Swynstead, on his marriage in 1288, on payment of a rose to the elder branch."

"He" was his father, Sir Robert. "The elder branch" appears to be to the family of his elder brother, Alexander.
