Hm. That's kinda weird. There was no European settlement in Galveston (then Galvez) at all until 1816, and those first structures were built by a French pirate to aid the early efforts of the Mexican rebellion against the Spanish (not the pirate Jean Lafitte, BTW, who basically took over the island and bay in 1817 and made it into his own "pirate city state" until he was forced out in 1821).
But, yep, point well taken. There were a lot of folks bearing the surname Knight in Texas in the 19th century...just not many before formation of the Republic in 1836. There was a James Knight among the Old Three Hundred, the first settlers in Texas brought in by the "empressario" Stephen F. Austin between the years 1821 and 1823.
