Lady Isabel de Weston, of Berkeley

From page 335 of Collections for a History of Staffordshire: Vol. I By William Salt Archaeological Society

This Sir John de Weston was twice married, first to Isabella de Bromley, sister to Mr. Stephen de Bromley, afterwards Rector of Blymhill, which Isabella died in 1317, having bequeathed her body to be buried in the Church of St. Andrew at Weston. By her he had an elder son, Thomas de Weston, and several daughters, who eventually became co-heirs to the Weston estate.
Sir John married 2ndly Isolda, daughter of his cousin William de Newton, by whom he had three sons, John, Robert, and William, and two daughters, Alice and Agnes. Sir John de Weston was living in 20 Edw. III., but deceased before May 1349, when his son, Thomas de Weston, was in possession of the Manor of Weston under Liziard.
Thomas de Weston, Lord of Weston under Lusyerd (as it was then written), as patron of the Church of Blymhill for that turn, presented Mr. Stephen de Bromley,chaplain,who was admitted and instituted in August, 1349. ... Thomas de Weston must have died soon afterwards, leaving an only son, Robert, who died in the following year, when the said Robert's aunts, the sisters of the whole blood to Thomas de Weston, succeeded to the inheritance.
These ladies were Elizabeth, who first married Sir John de Whyston, and 2ndly Sir Adam de Peshale, by both of whom she had issue; Helen, wife of William de Trumwyn; and Isolda, wife of Thomas le Champion. Erdeswick speaks of two others, namely, Joan, wife of William de Burgh and Ann. The Manor of Weston was certainly divided into five equal parts, so that the natural inference is that there were five such sisters and co-heirs; but I find no mention of either Joan* or Ann in the several settlements of lands which were made by Sir John de Weston on his younger children, nor do I meet with any evidence whatever of their having held any portion of the Weston inheritance; and I am disposed to think that there were but three such sisters only who survived their nephew Robert, or whose issue had any share of his lands.
