According to the Handbook of Texas, the community had a population of 125 in 2000. The community derives its name from Daniel G. Martin, who settled on Heifer Creek and owned a gin and gristmill that were built just before the start of the American Civil War. It was located a mile southeast of where it currently stands today. Two churches in the community were Holly Springs Methodist Church and Liberty Community Baptist Church. A post office was established at Martin's Mill in 1879 and remained in operation until after 1930. Its population was 75 in 1890 and went down to 40 two years later. A log building that was built here in 1875 was used as a community center and a church as early as 1900. A tornado hit Martin's Mill on May 25, 1907, and swept away all of its businesses. A Baptist congregation moved here from Sand Springs in 1919 and had a cotton gin, a corn mill, general stores, and other businesses. The population boomed to 200 in 1927 then plunged to 58 in the 1930s and went back up to 200 by the end of that decade. There was a church, a cemetery, a seasonal industry, and several scattered houses here in 1936. It then received electricity in 1944. The population was reduced by half in the late 1960s and went up to 125 from the early 1970s through 2000. A 1984 county highway map showed a church and some businesses in Martin's Mill.
