Interesting information on the ancestry of the 'Bilton' family which married into the Fauconbergs...
"In the 'Middle division: Bilton', A History of the County of York East Riding: Volume 7: Holderness Wapentake, Middle and North Divisions (2002), pp. 123-128, assumptions are made that 'Joan' is the widow of John of Bilton as she was the dame who passed the lands over to Isabel, daughter of John, who married either Robert or William Plessington.
However, in 1302, the Notes on the Religious and Secular Houses of Yorkshire, states that there was a warrant issued by Beatrice widow of Saer de Bilton, guardian of the body and a part of the lands of John, son and heir of Saer de Bilton, to Nicholas de Langetone for the third part of eight tofts and eight bovates of land in Didensale, which Beatrice, widow of Saer de Bilton, claims in dower. Joining her plea was Aymo de Quarto, Provost of everley, and Joan, widow of John Wake, guardian of other parts of the lands of the said heir.
Is theJoan that was mentioned in the first referenced title, Joan, widow of John Wake, who was vested as a guardian of the land - likely insuring it was justly passed to the proper parties? Or possibly Joan Aumale who was her paternal grandmother? The Aumale family also brought estates into the Fauconberg holdings. Or was that indeed the name of Isabel's mother, and Beatrice was a second wife?
It appears that in The Calendar of Patent Roles, 5th November 1301, that a plea was entered for the pardon of a John de Bonyngton for the murder of Thomas Heslerton and the rape of Beatrice, late the wife of Saer of Bilton. Perhaps the other guardians of the land were present for good reason as robberies, trespasses, and consequent outlawry appeared to be rife on the estate. This appears to have arisen from a formal grievance filed 12th August 1301 also in The Calendar of Patent Roles, where ..."The like to William de Bereford and Peter Mallore, on complaint by Beatrice, late the wife of Saer de Bilton, that John son of Robert de Bonynton, William Whitheved, Gilbert le Scot, Bateman Odel, and Nicholas de Kernetby took her at Marton by Bridlington, co. York, and imprisoned her, carried away her goods and assaulted her men." The property of Saer de Bilton was also subject to much outlawry prior to his death."
