If Gilbert de Stoke married Isolda Brereton in 1272, as I have read, and their son was the first Brindley, Brundelegh de Brundeley, who was the Richard de Brundeley mentioned below?
From Welsh Records – Calendars of Deed, Inquisitions, and Writs of Dower, Enrolled on The Plea Rolls of The County of Chester.-Edward 2. 1311/12 (4th year of Edward II’s reign) Brundeley, Hugh son of Richard de, and Richard de Brundeley and Margery his wife. Fine – 20 acres of land in Halghton. (4 & 5 Edw. 2. m. 2 d.)
So, in 1311/12 their was a Richard Brindley and his wife Margery and their son, Hugh. If Richard had a son who was old enough to be mentioned as receiving a fine alongside his parents, surely he must have come of age. In this case did Richard and Margery marry about 20 years earlier, 1291 and was Richard therefore, born about 20 years prior to that, 1271? This Richard must have been born at a similar time to Brundelegh de Brundeley, supposedly the first of that name unless Gilbert de Stoke and Isolda actually married much earlier. By the way there is also a Robert de Brundeley mentioned at this time.
