Nearby, the small town of Trinity Mills was built on the Trinity River at "Witts Stream Mill" in 1853. It was a bustling commercial center and had much trade with Carrollton until the early 20th century, when the town dissolved into other local municipalities. Parts of Trinity Mills were absorbed into what is now Carrollton and a major thoroughfare in Carrollton is named for Trinity Mills.
