Prior to the Gwinnett Historical Society buying the house and 3 acres in 1978, owners other than the Winn family included the Ambrose and Sims families and the Baptist Association of Texas. Jacob Marquis Ambrose (see portraits in upstairs bedroom) conveyed 500 acres of land that included the Winn House to his son-in-law, Jackson Longstreet Sims, Sr., November 30, 1896. About 1918 Jack Sims spruced up the house, painting it green with white trim on both the windows and “swinging porch.” The historical society bought the property October 26, 1978, from the Baptist Foundation of Texas and the Rev. Olyn Sims, son of Jack L. Sims, Sr.
