I'm guessing from his middle name, Jose is a son of your couple, and Santos is probably a brother.Combined info from TX Dth Idx Online 1964-1998 and SSDI:
Jose Rabago Espadas, b 8 Nov 1897; d 3 Jul 1987 Uvalde Co, TX; last residence Uvalde, Uvalde Co, TX; SS card issued in TX.
Santos R. Espadas, b 25 Dec 1899; d 16 Jan 1985 Uvalde Co, TX; last residence Uvalde, Uvalde Co, TX; SS card issued in TX.
You might try the Uvalde Co, TX GenWeb site, some GenWeb counties are putting their cemeteries online and you might find Francisco and Antonia buried there, too.If cemeteries not on the county site, be sure to check the archived section of the TXGenWeb Project, too.
I would post a query on the GenWeb and GenForum site for Ulvade Co, TX.GenWeb counties generally receive more hits, but you never know who is using which site, and GenForum is good, too.
If you go to the SSDI site, just type in surname of Espadas, there are only 16 with about half of them in TX, and most of those show last residence in Uvalde, TX.I think many of the family must have stayed right there.Happy Hunting.
