097 of 254: McMullen County Courthouse, Tilden, Texas. County Population: 707, that's all
"By 1836, when Texas seceded from Mexico, the area remained populated almost entirely by the Indian bands that roamed through the area.
"Neither the Republic of Texas nor the Mexican government could establish control over this strip of contested land, and it became a haven for outlaws and desperate characters.
"When McMullen County was officially established from parts of Bexar, Atascosa, and Live Oak counties in 1858, the area had only begun to be settled.
"McMullen County was named for John McMullen, the Irish empresario.
"In 1858 a group of about thirty people established a settlement where Leoncita Creek met the Frio. By fall of that year they had built eight to ten crude dwellings and soon afterward began to cut a road to meet the San Antonio-Laredo road that lay to the west. Dubbed Rio Frio, later Dog Town, and then Tilden, this was the first permanent settlement in the county.
"In 1877, when McMullen County was officially organized, Dog Town was chosen as the county seat. That same year, the town was formally surveyed, and its name was changed to Tilden."

I visited this county and photographed the courthouse on April 13, 2011. I drove through the county in October 2011 and discovered a substantial increase in traffic and inhabitants due to the Eagle Ford Shale Oil activity.
