John M. Dorr (Dor, Door), pioneer settler and Nacogdoches county official, moved to Red River County, Texas, in 1830 and served for a time as secretary to Benjamin Rush Milam. In 1834 he proceeded to Nacogdoches, where he became secretary of the ayuntamiento on January 1, 1835. He married Eliza Frisby in Nacogdoches on August 25. On January 1, 1836, he was elected a judge of the municipality and on August 30 issued a call for the organization of a local militia. Sam Houston's appointment of Dorr, on November 8, 1836, as one of three commissioners to treat with the Indians was not confirmed by the Senate. On November 16, however, Dorr became primary judge of Nacogdoches. In 1837 he bought land there and purchased an interest in Travis, a landing on the Angelina River. On September 25, 1839, he made a deposition in Galveston concerning Vicente Córdova. Dorr died sometime between 1839 and 1845.
