Dallas Texas
The origin of the name of the town of Dallas is obscure. We have no primary evidence from John Neely Bryan, the founder of the town, indicating exactly how he chose the name "Dallas." Bryan (1810-1877), a trader, farmer, lawyer, and land speculator, is well documented in legal and business records but left few personal writings. Frank M. Cockrell, an early pioneer who knew Bryan, recalled that Bryan asserted "the town was named for my friend Dallas". (WPA Dallas Guide and History, p. 43, History of Early Dallas by Frank M. Cockrell, and Dallas: The Deciding Years by A. C. Greene, p. 7).
There has been much speculation about exactly who that person named Dallas was. Cockrell believed that it was George Mifflin Dallas, vice-president of the United States during the administration of President James K. Polk. Dallas County is generally believed to have been named for George Mifflin Dallas since Polk County, named for President Polk, was created on March 30, 1846, the same day that Dallas County was created. The city, however, is a different story.
No evidence exists that Bryan ever knew George Mifflin Dallas. In addition, the town of Dallas bore that name at least three years before the county was created. George Mifflin Dallas had no documented interest in Texas until he made a casual reference favoring Texas statehood in an 1844 letter to a senator from Mississippi—again, after the town of Dallas, Texas, was named.
