He was one of two children born to Joel and Lucy (Ragland) Terrell. He was born in either Fairfax County (or Louisa County), Virginia. He moved with his parents to Wilkes County, Georgia about 1784. He pursued classical studies. Terrell later graduated from the University of Pennsylvania School of Medicine at Philadelphia and commenced practice in Sparta, Georgia.
In 1818, Terrell married Eliza Rhodes, the daughter of William Rhodes. To this union was born a daughter, Lucy.
Terrell was elected as a Democratic-Republican to the United States House of Representatives, serving in the 15th and 16th Congresses serving from March 4, 1817, until March 3, 1821. He declined to be a candidate for renomination in 1820, and resumed the practice of medicine.
After he left Congress, Terrell devoted more of his time to the promotion of Agricultural Science than his medical practice. In 1853, he donated $20,000 to the University of Georgia to establish a Department of Agriculture.
Terrell County, Georgia, created in 1856 from portions of Randolph and Lee Counties, was named for William Terrell. Dawson, the county seat, is named after William C. Dawson, his daughter's father-in-law.
