Kohr's grandson, Conrad Kohrs Warren, spent many summers with his grandparents and gained a passion for ranching by watching and helping his great-uncle, John Bielenberg, on the ranch. In 1932 he took over ranch management. Like his ancestors, Con Warren continued to improve ranching operations. He built the red barn in 1952 and also built other structures such as the granary, blacksmith shop, and feedlots. The Warren house was a wedding gift ordered from the Sears catalog by his grandmother, Augusta Kohrs. Con Warren and his wife Nell made it a home for their son and daughter, and Warren continued to live there until he passed away in 1993.
