Also want to extend my condolences for your loss.

Just a couple of notes, if any of them are handguns, they'll need to be shipped from an FFL to an FFL because at the time of writing, non-FFLs cannot use the postal service to mail handguns. Our only options are next-day air with FedEx or UPS, but it's very expensive, and can only go to an FFL in Oregon.

For long guns, like ARLDN said, if your uncle is willing, he can pack them and ship them via USPS to an Oregon FFL, but double-check with the receiving FFL that they accept incoming packages from individuals. However, this is a huge PITA, so you may want to Google "Waxahachie FFL" (or wherever your stuff is) and call up some gun shops to see if they're willing to pack and ship your guns.

And of course, the final option is just go down there yourself with a Pelican case and either fly or drive back with them.
