Research Notes:
identification of Isabel, the widow of Ralph de Plaiz (d.1283) [vol.10, p.539]
with Isabel the wife of John Marmion (d.1322), which was pointed out by Douglas Richardson. Apart from other circumstantial evidence, the Victoria County History of Sussex, vol.7, p.54 (Iford) refers to British Library, Add. MS 39,373, fols 181, 191 to support the identification.
This manuscript is a modern (Victorian?) collection of extracts from the de Banco rolls, Henry III to Edward II, and on fo.181 is an entry dated 1301 in which Ralph de Playz is indeed described as formerly the husband of Isabel, the wife of John Marmion.
Comparing the remainder of the information in the manuscript with the account of Plaiz in CP, there's some additional information, and one statement that contradicts the account:
(1) The second entry, dated 1303, is a suit brought by Philippa the daughter of Richard de Plaiz against Henry de Guldeford, guardian of Richard, the son and heir of Giles the son of Richard de Plaiz. Presumably this is the same Philippa de Plaiz mentioned in 1302 (CP p.538, note m) - if so this confirms the suggestin of CP that she was a daughter of Richard. A sketch tree accompanying the abstract shows Giles' widow Joan as the mother of his infant son Richard (as might be assumed, as CP mentions no other wife).
(2) The first entry describes Joan the widow of Richard de Plaiz as the mother of his sons Ralph and Giles (again, CP mentions no other wife).
(3) The first entry also states that Alice who was the wife of Ralph de Playz, grandfather of the aforesaid Giles, holds certain lands in Norfolk and Kent in dower. [Ref: Chris Phillips SGM 2/24/2002-081355]

1301: 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 [Ref: CP++ Marmion 12/31/2006 (CP VIII p520)]

it is possible that she was the daughter of Alexander Peck, but for this there is no sufficient evidence available [Ref: CP VIII p520(j)]
