This was from the Provost's list. I'll check to see if others were left off. Actually, we know him as Captain Tivy.

Marker #: 5265000724 -- Captain Joseph A. Tivy - In 1837 Joseph A. Tivy (1818-92) and his two sisters came to Texas from Canada. After serving as a Texas Ranger, Tivy joined his sisters in the California Gold Rush of 1849. There they operated a hotel and he later served in the State Legislature. After returning to Texas in the late 1850s, Tivy fought in the Civil War, attaining the rank of captain. A surveyor, rancher, and Texas Legislator (1873), he served as the first Kerrville mayor in 1889. During his term of office he gave land for the city schools. He and his wife Ella (d. 1888) and his sister Susan (d. 1901) are buried on nearby Tivy Mountain. (1980)

Perhaps he was not a Kerr County resident at the time of his service...
He joined the 31st Texas Cavalry Regiment which was organized in the Dallas Ft Worth area but which also pulled men from Karnes and Fannan Counties. In May, 1862, and led by Col. Trezevant C. Hawpe, a Dallas businessman, the 31st started moving north. It is at Ft. Washita in August 1862 that the 31st completed its organization. It’s first battles and training were in the Indian Territories. Joseph Tivy was elected 1st Lt of Company A because of his age and military experience. (Captain Hayes ran a rough bunch of Rangers and not a lot of military training.) With the 31st organized it was added to the 22nd and 34th Texas Cavalry Regiments into a new Brigade which is where the name problems begin. There is some problem with the correct name and brigade, but the unit was the 31st Texas Cavalry Regiment, CSA (Hawpe’s Regiment).

He arrived in Kerrville in 1872 with two of his sisters to live on property he had obtained in 1842
