From Richard de Cornwall circa 1255 - 1296
Richard was probably born sometime around the mid 1250s (1), the illegitimate son of Richard, earl of Cornwall (5). His mother is unknown, although it has often been claimed, without any proof, that she was named Joan de Valletort.
He was made Sir Richard by 1277, at which time he was a knight serving for his brother Edmund, earl of Cornwall (4). He maintained a close relationship with Edmund throughout his life, often witnessing Edmund's grants, travelling overseas with him, and fighting alongside him.
He married a woman named Joan (7)(10)(11), and their eldest known son Edmund (7)(18) was born around the late 1270s (8). They had another son Geoffrey about 1288 (12)(19). They may also have had another son Richard and a daughter Joan, amongst others (13).
In 1280 he went overseas with Edmund his brother, presumably on state business (14). In 1286 he had his seal stolen (15). In 1290 he witnessed a grant by his brother Edmund, giving land to Hailes Abbey, which his father had founded (16).
He died in the Siege of Berwick in 1296 (17). His wife survived him by at least 24 years (11)
