Records that survive
These are the record series from Atascosa County that were microfilmed for the Texas State Library and Archives Commission (TSLAC), with the office that kept each and the earliest and latest years filmed. A span can include gaps. Not every county, or every record in a county, was filmed.
The Texas State Library's guide doesn't list microfilm for Atascosa County. Ask the county clerk what survives, and check FamilySearch for filmed records.

Boundaries and parent counties
Formed from: Bexar County
Check the parent county for earlier records: Bexar County
Later formed partly from Atascosa County: Frio County, McMullen County
Records stay with the county that created them. If your ancestor lived here before 1856, search the parent county. The Atlas of Historical County Boundaries shows each boundary change.
Research tip
Texas land was granted by the state, not the federal government, so an ancestor who received land directly from the government will usually have a file at the General Land Office as well as deeds in the county.
