"a Texas origin for Puerto Rico gAHB instead of a Brazil origin" certainly may exclude Brazil as a source for PR, but does not eliminate a common *Central American* source of both the Texan and the PR genetics.

If I were looking for a common source of PR bee genetics, I'd start looking in Venezuela, as one can island-hop up the windward island to the leeward islands, with the longest sail between islands being St Kitts to the US VI, just over 110 miles. This is a very popular pastime for anyone with a sailboat, and is also a profitable route for exactly the kind of rustbucket cargo ships that serve the islands and are likely to inadvertently carry bee swarms - the short distances tend to encourage lax maintenance, lax biosecurity, and so on.
