Actually, most knightly shield-bearer and attendant do not sign themselves "Esquire".

They don't want anyone to mistake them for lawyers.

Good point.

That, plus the fact that a) there are no more jousting knights, so b) there are no more squires, and c) squires likely couldn't read or write anyway, leads me to ban the use of Esq. from my personal fiefdom.
