From the battle of Nacogdoches until the early days of the Texas Revolution in 1835, he pursued his career as a merchant and enlarged his fortune by purchasing cheap land grants. Roberts enlisted in the Nacogdoches Independent Volunteers on October 4, 1835, as a first lieutenant (he was later promoted to captain) under Capt. Thomas J. Rusk and saw distinguished service in the siege of Bexar (November 25 - December 5). He was elected a delegate to the Convention of 1836 at Washington-on-the-Brazos and signed the Declaration of Independence March 2, 1836, after which he quickly departed for Nacogdoches. After the revolution Roberts formed a partnership with John Durst and George Allen to engage in the mercantile business at a location across Fredonia Street east of the Old Stone Fort on the town square in Nacogdoches. The next year the firm was doing business as Roberts, Allen, and Company; in 1838 Durst bought out Allen, and the firm of Roberts, Durst and [Frederick T.] Phillips was formed. Later that same year the business was sold to one Francis von der Hoya.
Meanwhile, on May 18, 1837, Maj. Gen. Thomas J. Rusk appointed Roberts quartermaster of the Texas Militia; between that date and July 10, 1839, he served as quartermaster of militia on four different occasions, for a total of more than seventeen months. During this time, by an act of the Congress of the republic dated January 10, 1839, he was authorized to adopt Harriet's son, John Collier, and change his name to John F. Roberts. Roberts and Durst were adventurous in business, but for Roberts the speculation ended in the fall of 1838, when there began a series of law suits, the nature of which is not known, that resulted in his financial ruin. In the late 1840s he first sought to protect the financial interests of his wife and stepson in the estate of Robert Collier. About this time he entered the grocery and saloon business in Nacogdoches - first on the east side of the town square, and later in the Old Stone Fort, title to which had passed into Harriet's hand. He operated this business until his death on August 9, 1871. His body was interred in the old Oak Grove Cemetery in Nacogdoches. Source
