Fannin County, Texas: History
The county was named for James Fannin, who commanded the group of Texans killed in the Goliad Massacre during the Texas Revolution. James Bonham (the county seat's namesake) sought Fannin's assistance for the Battle of the Alamo, but Fannin was unable to provide it.
The county was created in 1837 and organized the next year. Fannin County is a part of the Texoma region.
