In the early 1800s, settlements began to take place in the area that would one day become Ellis County; however, full colonization of this area was slow until 1843, when Sam Houston finalized peace treaties between several of the indigenous inhabitants of the region and the Republic of Texas. The earliest inhabitants of this area were the Tonkawa people, but other tribes also hunted in this area including the Anadarko people, Bidai,Kickapoo, and the Waco.The future Ellis County area of the young Republic of Texas was known as the Peters Colony, named for a Louisville, Kentucky-based land grant company consisting of English and American investors. The young Republic empresario grant program encouraged settlements in North Texas in 1841. The few settlers who lived in this region trapped animals and sold their pelts, and would also trade goods with the natives. The majority of Ellis County's original settlers came from the southern half of the United States.Among the earliest settlers, the area that would later become Midlothian included the families of William Alden Hawkins and Larkin Newton, who moved to the area in 1848. For Hawkins to claim his 640 acres (260 ha) of land from the Peters Colony group, he was required to build a house on the property he chose along the mouth of Waxahachie Creek before July 1, 1848. The structure was built before the required deadline, and the land near the present day Hawkins Spring went to the Hawkins family.In 1883 the name "Midlothian" was accepted by the local population. With the coming of the railroad, Midlothian grew and was incorporated in April 1888.
