DeWees traveled in Mexico in 1826 and 1827, then took up residence in San Antonio, where he lived for almost two years before returning to his home on the Colorado. Beginning in 1837 he held a series of public offices in Colorado County, including justice of the peace, associate land commissioner, and associate justice of the county court. In 1865 he was again elected justice of the peace for Precinct 1 of Colorado County. Later that year he was appointed to a term as county treasurer by provisional governor A. J. Hamilton. But DeWees's political career and reputation were ruined in 1866 when he was charged by his successor with misappropriating $1,200 in county funds and was successfully sued for that amount in district court. His appeal of the decision was denied in 1870.
DeWees married a daughter of Austin colonist Benjamin Beeson, probably named Lydia, in 1823 and eventually became the father of two children. His wife apparently died before 1850, and DeWees probably married a German immigrant named Angelica. In the early 1850s he covertly collaborated with writer Emmaretta Cara Kimball Crawford in producing a journal of his pioneering experiences that purported to be a compilation of his letters to a Kentucky resident named Cara Cardelle; this volume of dictated reminiscences, actually written by Emmaretta Kimball, was published in 1852 under the title Letters from an Early Settler of Texas to a Friend. DeWees died in Colorado County on April 14, 1878.
