Based on geography, you may have found leads to your Brewer(s)? Silverton and Quitague are in Briscoe County, Flomot is in Motley, and Turkey is in Hall. These counties are in the panhandle area near the Oklahoma border. Matador is in Hidalgo County near the border with Mexico. In my initial search, William Dallas and Ellen were living with their uncle (Samuel R. Conner) in 1910 Garvin, OK. Samuel R. Conner relocated to Harlingen in Cameron County. Cameron is next to Hildalgo County. John Thomas Brewer registered for WWI Draft in Cameron County and named his uncle Samuel R. Conner (of Harlingen) as next-of-kin. We are part of the same generation, so you've got help! I'll get "deeper" into this as time permits. Now, what was your uncle's surname? It would be a big help to know his full name and lifespan. I'm "shooting in the dark" and making suppositions without "clear links"!
