In January of 1889, Sam married Emma Henry in Milam County, Texas. Six years later, in January of 1895, Sam's little sister, Berta Mary, married Emma's twin brother, Edgar, in Houston County, Texas. Each couple had multiple children before William Harden Sharp was born to Sam & Emma in September of 1904, and Robert E.
