BARONY of BASSET (of Sapcote) (I)
RALPH BASSET, son and heir, under age in 1330. In July 1369, being then aged over 40, he became, by the death of his cousin, Robert, Lord Colvill one of the two coheirs of the estates and Barony of that family, inheriting the Castle and Honour of Bytham, co. Lincoln, Thornton Steward, co. York, &C. In consequence, doubtless, of these acquisitions, he was summoned to Parliament 8 January 1370/1 and 6 October 1372, by writs directed Radulfo Basset de Sapcote, whereby he is held to have become LORD BASSET. He fought in the French wars and was one of the heroes of Crecy.
He married 1stly, about 1346, Sibyl, sister of Thomas ASTLEY [3rd LORD ASTLEY], and daughter of Sir Giles Astley, by Alice, 2nd daughter and coheir of Sir Thomas DE WOLVEY. He married, 2ndly, Alice, daughter of John DERBY. He died s.p.m., 17 July 1378, when the Barony fell (according to modern doctrine) into abeyance between his two daughters and coheirs. Will, as Ralph Basset, knight, Lord of Sapcote, directing his burial to be at Castle Bytham, dated there the Monday after the Ascension I I May 1377, proved at Lincoln. His widow, who married Sir Robert TUCHET, and afterwards Sir Anketine MALLORY, died a widow, 12 October 1412, and was buried at Stamford, near her last husband.

Note: I disagree with CP in this situation. Due to the fact that Sibyl was born before 1317 (and probably earlier), I think that Sibyl and Ralph were the mother and father of this Ralph, and were born well before 1346.
