Try to get some pics next time you go. There are a lot of Texas listed in the FH section on Aquabid, so I'm guessing FH and Texas will cross. FH seem to be the wild card in SA breeding though. I'd bet the list of what they won't pair up with is much shorter than what they will.
I'd be careful gifting your Aunt with anything with FH in it though. I've had some rehab FH here and the only things they could ever live with were turtles. They're pretty, but they're right bastards.
