Agnes de Barton was descended from Edith de Barton, daughter of Albert Grelle, or Greslet, who was the fourth Baron of Manchester. The first Lord of the Manor of Mamecestre, or Manchester, was also Albert Greslet, who, as a favourite of Roger de Poictou, probably occupied a high position at the Courts of William I. and William II. It is thought that he received the grant of the Barony of Mamecestre about 1086, and, until the death of Thomas, the eighth Baron, in 1310, the Barony continued in the hands of the Greslets. Thomas having no male issue, he left the Barony to his sister Joan, who had married Sir John de Ia Warre, Baron of Wickwar, County Gloucester. Albert Greslet the Younger, as the fourth Baron is often called, died in 1182, and was succeeded by his son, Robert. His daughter Edith married Gilbert, son of William de Notten, of Yorkshire, in 1190. Included amongst the lands paying knights' fees in the County of Lancaster in the opening decade of the thir-teenth century were those of Gilbert de Notten, who held in the right of his wife (Edith de Barton) "fourteen oxgangs of the Lord the King in Thanage, for which he paid 26s. annually."
