|SOME NOTES ON MEDIEVAL ENGLISH GENEALOGY|
Volume 10, page 538:
He [Sir Hugh de Plaiz (d. 1244)] m., 3rdly, Alice (----).(f) ... His widow was living in 1275.
Who claimed dower from Richard de Plaiz in 1256 (Sussex Fines, Sussex Rec. Soc., vol. vii, no. 607), receiving the manors of Toftrees and Feltwell, and the advowson of Weeting, Norfolk, and the manor of "Leye,",Kent.
Apparently she was still living 1301, when it was stated that she held lands in Norfolk and Kent in dower [modern abstract, from the de Banco roll, Easter Term, British Library, Additional Manuscript 39,373, fo.181; the abstract describes her erroneously as the widow of Ralph (not Hugh), grandfather of Giles de Plaiz].
Volume 10, pages 538, 539:
He [Richard de Plaiz (d. 1269)] m. Joan ... In Jan. 1270/1, for £10, his widow had licence to marry whom she would of the King's allegiance; she was living in 1302.
Joan was stated in 1301 to be the mother of Richard's sons and successors, Ralph and Giles [modern abstract, from the de Banco roll, Easter Term, British Library, Additional Manuscript 39,373, fo.181].
Volume 10, page 538, note m:
The Philippe de Plaiz, Joan de Huntingfield and Joan de Plaiz who in 1302 held ½ fee in Feltwell and Weeting (Feudal Aids, vol. iii, p. 427) may have been his [Richard de Plaiz's (d. 1269)] daughters.
This suggestion is supported by the appearance in 1303 of a Philippa, daughter of Richard de Plaiz, in a suit against Henry de Guldeford, guardian of Richard, the infant grandson of Richard de Plaiz (d. 1269) [modern abstract, from the de Banco roll, Trinity Term, British Library, Additional Manuscript 39,373, fo.181].
Volume 10, page 539:
He [Ralph de Plaiz (d. 1283)] m. Isabel (----), and d. s.p., shortly before 6 Nov. 1283.
Isabel remarried to Sir John de Marmion (d.1322). In an order for the assessment of dower in Easter Term 1301, Ralph de Plaiz is referred to as formerly the husband of Isabel, the wife of John Marmion [modern abstract, from the de Banco roll, British Library, Additional Manuscript 39,373, fo.181].
[The evidence that Isabel married both Ralph de Plaiz and Sir John Marmion was pointed out by Douglas Richardson in December 2001]
