Notes

From https://williamhenryfluen.de.tl/William-Thwaites.htm

In 10 Hen VI (1431/32) John Thwaites enfeoffed (?) Sir William Gascoigne with 'my manor of Denton', but John Thwaites and his wife Isabel [Ryther] were regranted Denton with a new entail, first to their [future] male heirs, then to John's son Thomas and his male heirs, then the male heirs of John's daughter Matilda married to John Middleton of Stockeld, and then the right heirs of John. This was likely associated with John's marriage to Isabel Ryther. John Thwaites again granted Denton then to his son Thomas, and Thomas' wife Alicia dau of Thomas del Hay in 37 Hen VI (1468/69). By this it is clear that Thwaites had no male issue by his second wife, and Thomas m. Alicia de la Haye was the heir of Denton. Mathilda (Maud) Thwaites was perhaps the eldest daughter by his second wife, Isabel Ryther.
