There are some historians who believe this is a misreading of the historical record.
There was a community in Kerr County called Brownsborough that was about four miles downstream of Comfort where some early legal events occurred. Today that community is in Kendall County. All that remains today is a cemetery and some scattered buildings. It is unlikely there would have been two communities in the same county with the the same name.
In the Galveston Flakes Daily Bulletin of June 16, 1868, June 25, 1868, and many other issues, both Brownsborough and Kerrville are mentioned as separate places.
As proof, at the first county court session May 19, 1856, a second class road was ordered laid from Kerrsville to Brownsborough by way of Comfort.
Old maps also show Brownsborough being east of Comfort.

road shall be lain out and located on the best
and nearest route without partiality or
If Kerrville were Brownsborough, it would not have been possible to locate a road from Kerrville to Brownsborough. I have seen a few referrals to Brownsburg. More likely Kerrville was known as Brownsburg rather than Brownsborough.
