In my research about the TB Hospital in Carlsbad, TX, I found a place that may possibly house the records from the old TB hospital that was located in northern Tom Green County. Try the Texas Center for Infectious Disease in San Antonio, TX. The address is P.O. Box 23340, San Antonio, TX 78223-0340. The fax number of the Client Records office is 210/531-4514. It is my understanding that the records from the TB hospital were sent to the San Antonio Chest Hospital, which was renamed the Texas Center for Infectious Disease. Someone there might be able to at least tell you where the records are archived now.
