Osborne Bragg Robertson, born November 23, 1861 in Mississippi, was the ninth of eleven children of L B T and Rhoda West Robertson. At fourteen, Osborne's family moved to Waelder, and later attended Scherrer's Art & Business College in Galveston. On March 30, 1887, he married Susan Miller, daughter of Robert and Sara Hopkins Miller. Her father, Robert, had settled in Hopkinsville in 1860 and moved to Waelder in 1873 to open a mercantile business.
In 1887, Osborne partnered with his father-in-law in the mercantile store. In 1889, he opened a drug store but soon shifted his focus to land transactions. He became one of the original stockholders of The Farmer's State Bank of Waelder and later became a key stockholder in the Gonzales State Bank & Trust Company. In 1914, Osborne acquired control of the Sunset Brick & Tile Company and also engaged in farming and lumber. He served in the Texas Legislature from 1912 to 1914. During the Great Depression, Osborne and his partners used their personal wealth to stabilize the Gonzales bank, ensuring its survival and continued operation.
