=========================================
espoused, probably about 1470, Isabella Moore,[245] maternal aunt (through her sister Elizabeth) of the celebrated John, Lord Williams of Thame, and daughter (and, according to the contemporary law, coheiress) of Richard Moore, Esq. of Burfield, co. Berks, by his first wife, an heiress of the ancient house of Brocas, of Hampshire. By this marriage the D'Oylys became allied to the Lords Williams of Thame and acquired no small accession of family influence thereby; while they became entitled to quarter the arms of Moore, Brocas, Roches, and Banbury, the first of which was "Argent, a blackbird sable." The Moores could trace to the time of Edw. III.; their cadet had founded the family of Moore of South Fawley, co. Berks, Baronet, and the remaining coheiress of its senior line had merged in Lechingham, of Buckinghamshire
