From Genealogical Memoirs of the Extinct Family of Chester of Chicheley ..., Volume 1 By Robert Edmond Chester Waters

Edward Lord Montacute is erroneously stated by Dugdnle, (172) and in all the Peerages, to have married no wife except Alice of Brotherton, and to have left no children except Joan de Ufford; whereas it is certain from the inquest held after his death (168) that he married two wives and left two children by each of them. His wife Alice and her two daughters have been sufficiently noticed in the text. The name of his second wife is unknown to me ; but it is clear from the ages of her children that she married in or before 1357, and that she died at the birth of her son Edward in May or June 1361, for when Lord Montacute died on 14th July 1361, his next heir was his son Edward, then seven weeks old. (168) The youthful heir did not long survive his father, for it was found by an inquest held on 29th Nov. 1361 that the younger Edward died an infant, in the wardship of the King, on 27th Sept. 1361, and that his next heir was his sister Ethelreda de Montacute, who was then two years old and upwards. (168) The wardship and marriage of this Ethelreda were granted by the King on 1st Feb. 1366-7 to Alan Palmer, (111) and she occurs in 1390 the wife of Sir Hugh de Strauley Kt., of Redenhall, Norfolk.
