On December 15, 1834, Robert Hamilton, a native of Scotland, settled in the Red River area of Texas. Hamilton, a wealthy merchant, was one of the five men sent by Pecan Point and vicinity, or the Red River District, to the Convention of 1836 at Washington-on-the-Brazos.
Hamilton was probably the wealthiest man to sign the Texas Declaration of Independence. Because of his financial experience, wealth, and extensive connections, he was appointed, with George C. Childress, on March 19, 1836, to go to Washington, D.C., to seek recognition of the independence of Texas and establishment of commercial relations with the United States.
On December 20, 1836, President Sam Houston nominated Hamilton chief justice of Red River County, and in this post Hamilton authorized law enforcement in the area. He had large landholdings in Red River County
