Franklin County was erected and established in 1875, four decades after the independence of Texas, from land ceded by neighboring Titus County.  Although the origin of the county's name is not recorded, it is generally believed to have been named after Judge Benjamin C. Franklin, the first appointed justice in the Republic of Texas.

According to a study  ordered by the Mount Vernon Economic Development Corporation in 2013, the local retail trade area population is 12,771 people. The county has 720 homes valued at $200,000 or more, 70 homes of $500,000 or more, and 72 homes valued at more than $1,000,000. Most of these homes are centered on Lake Cypress Springs, which was twice voted the Most Beautiful Lake in Texas by the readers of Dallas' "D" magazine(2005, 2010). The lake is located about 10 miles south of Mount Vernon. The EDC study determined the average sale price of lakefront property on Lake Cypress Springs (2012) was $484,000, with 91 percent of the 1,400 water-front homes being second residences. This concentration of second residences causes the population of the county to increase between 3,000 and 8,000 people on weekends and during holidays, according to estimates by the Franklin County Water District,  which oversees the lake and its visitors.
