The English and Irish Brabazons claim from Jacques le Brabazon, who is said to have come into England with the Conqueror and to have borne the honourable distinction of "The Great Warrior." His posterity settled, during the early Norman reigns, at Betchworth, co. Surrey, and from them descended in an unbroken line the B.'s, earls of Meath, and baronets in Ireland. The name, variously written Barbauzon, Barbanzon, Brabazon, &c., is traditionally derived from the town or castle of Brabazon, in Normandy, but as no such locality can be found, its true source appears to be Brabant in Flanders, as stated in Lodge's Peerage of Ireland. In that duchy the village and castle of Brabancon had lords of the same name, one of whom espoused a grand-niece of Godfrey of Bouillon, King of Jerusalem, circ. 1100. See Geneal. Hist, of Fam. of Brabazon. Paris, 1825.

Originally from Brabant. In 1198 Thomas Brabençon paid a tine of 50 l. in Normandy, and Roger lent 15 l. to the king (Magni Rotuli Scaccarii Normanniae). The family continued in Normandy (La Roque, Mais. Harcourt, i. 604). John Brabazon paid a fine Oxfordshire 1247 (Roberts, Excerpt.). Roger le Brabazon was a justiciary 1294-1316, and William de B. was M.P. for Leicestershire 1313, and in 1325 had a writ of military summons to pass into Gascoigne. From this family descended the Earls of Meath and the Baronets Brabazon.
