Volume 11, page 475:
He [Geoffrey de Say (d. before 3 March 1321/2)] m. Idonia, da. of William (DE LEYBURN), LORD LEYBURN, by Juliane, da. and h. of Sir Henry DE SANDWICH. ... Idonia had Birling and Burham assigned to her in dower 15 Apr. 1322. Geoffrey had before his death settled his manor of West Greenwich on her and himself, with successive remainders to their sons Geoffrey, Roger and Ralph and the heirs of their bodies.

Douglas Richardson, in August 2002, posted evidence that Idonia was still living 14 November 1337 [citing Canterbury and York Society, vol. 48, p. 578 (1948)].
