(Foster, Joseph: Pedigrees of the County Families of Yorkshire, Vol. 2, West Riding. London. 1874)
09/06/1365 (39 Edward III) - Indenture between Elizabeth, late wife of Sir Nicholas de Wortelay and John Sayvill of Eland, by which the former granted to the latter, his heirs and executors, the custody of the lands and tenements which she had of the grant of Simon Simeon, and which Simon had had of the grant of Sir John duke of Lancaster, in Shitlyngton and Flocton by reason of the nonage of John son and heir of the said Sir Nicholas; likewise with the marriage of the said John; to hold until John be married and of full age and should he die unmarried and under age in like manner from heir to heir, until an heir be married and of full age and should he or any heir be married and die under age to hold until an heir be of full age, saving to Simon Simeon the marriage of the heir after one heir should have been married. (Clay, Charles Travis ed.: Yorkshire deeds: Vol 5)
A reasonable deduction may be that John Wortley was born on April 25, and came of age on April 25, 1373. He was duly married and was living in 1424. (Elizabeth was a daughter and coheiress of Adam de Wannervile, lord of Hemsworth, and widow of Sir Nicholas de Wortley, who died in 1360. Her will, dated at Hemsworth, Oct. 20 1382 for the connection of Hemsworth with the Wortley family as a result of this marriage. The more genial situation of Hemsworth seduced for a while the Wortleys from their antient hereditary seat.) (Clay, Charles Travis ed.: Yorkshire Deeds:, Volume 5)
