Some of the earliest burials in Texas are recorded in Mrs. Malcolm B. Biggerstaff, Four Thousand Tombstone Inscriptions from Texas, 1745-1870: Along the Old San Antonio Road and the Trail of Austin's Colonists (Oklahoma City: Oklahoma Historical Society, 1952; FHL book 976.4 V3b).
The Daughters of the American Revolution (DAR) collection also contains tombstone inscriptions from many Texas cemeteries. This collection is described in the "Genealogy" section of this outline.
