Belknap Street was named for Fort Belknap founded in Young County in 1851. Graham Street was named in honor of Fort Graham, founded in 1849 west of present Hillsboro on the site of an Anadarko Indian/Caddo village abandoned by Jose Maria [leader of the combined tribes] a few years earlier. Frey Street was named for John A. Frey [pronounced fry] who came to Stephenville in 1858 from Meridian. He operated a successful mercantile house and the family was important in banking. Funds from the Birdie Hartsough Frey Foundation were largely responsible for the creation of the Historical House Museum. The small, white office building at the museum was on the Frey ranch as a place for traveling black families that were not welcome in town. For many years Frey Street was a sandy path that ran along the stone wall that separated Stephenville from the ranch. Willard Chamberlain married Emily Marshall in December of 1838. They moved to Erath County in the 1870s and started a farm west of Stephenville near the present street named after them.
