"Bouchard: from a Norman personal name, Bou(r)chart, composed of the Germanic elements bourg ‘fort’ + heard ‘hardy’, ‘brave’, ‘strong’. Nickname for someone with a big mouth (possibly in either a literal or figurative sense), from French bouche ‘mouth’ + the pejorative suffix -ard."
Apparently, the motto is "Do Honor" and I must humbly say that I do indeed honour both possible meanings. ;)
Do honor... How Klingon! Love it! :P
