In one late ep a fellow wearing a cowboy hat showed up claiming to be Tony's cousin from Texas. Weird bit about them being related as they hardly seem to know each other. Didn't Anthony say they were actually second cousins? If they're just 2nd cousins it makes more sense.

Yeah, Tony said something like that to Roger when Roger started getting mad that Tony's cousin just sold him (Roger) a fake ring. The cousin Arville was played by Gabe Dell of the Bowery Boys.
