I am going through Ed Blackburn, Jr.’s book “Wanted: Historic County Jails of Texas” and looking for references to vanished calabooses. So far, I have found quite a few.  In a few hours, I will have added information for Austin, Bailey, Bastrop, Bee, Bell, and Brewster counties.  There will not always be Sanborn maps to check against the statements in his book but he does cite his sources.  Some of the jails described by Blackburn were two-story buildings that do not fit my initial definition of a calaboose but they are included because they are reported to be the first in the counties and they were unusual in their construction.
