Oh wise one, profitbob, no. Esquire (ESQ) in the middle ages is defined as a squire, or aspirant to knighthood, attendant upon a knight. Esquire and Squire are terminal titles (of which British royalty is full of) both dereived from polite recognition of (in England) "A country gentleman", more especially the chief judicial proprietor in a common district; leaning toward a young man of gentle birth who, as an aspirant to knightghood, attended or attends upon a knight; an esquire.
British autocracy tended to persue squirearchy, where rule or government was effected by a squire or squires. We see many cocky personalities, like Edward Tabash, Esq., a hollywood attorney for liberal rich people, wearing the esq like a badge of honor when in truth it is concocted and elitist. Edward Tabash Esq currently represents many atheist organizations in New York. Chow.
