I looked through the cemeteries that are indexed and online but didn't find George.
Here's the list of web sites:
Tombston Transcription Project, http://usgwtombstones.org/texas/pecos.html
Genealogy Trails Cemeteries of Pecos County, Texas, http://genealogytrails.com/tex/bigbend/pecos/cemetery.html
TXGenWeb Pecos County Cemeteries, www.rootsweb.ancestry.com/~txpecos2/cemeteries.html
Cemeteries of pecos County Texas, www.cemeteries-of-tx.com/Wtx/Pecos/ListPecos.html
Sometimes where a person was buried will be included in their obituary. You can contact the Pecos County Public Library and ask for a copy of his obituary. Successful Searching!
