Yes, older Texans pronounce it Gal VEZ ton. because the person who founded the settlement was named Galvez, with the accent on the last syllable (don’t know how to get an accent out of this keyboard).
Dad is ninty and pronouces it that way because that’s how his family here in Indiana said it. The family were greenbacks* who came up the Mississippi and the Ohio Rivers. The settled in Southern Indiana and ran one of the early stone quarries (Before Oolitic was discovered) Several Courthouses in the southern part of the state have their names attacked as stone masons.
My sis jokes if they send the greenbacks back will we have to go too.
