William Hickman Wimberley was the son of Pleasant Wimberley and his wife Amanda Julian Jackson Wimberley. He was born on August 14, 1859, in Burleson County, Texas.

William grew up to marry twice. His first wife was Johnie "Eller" Amanda Leath. They married on August 21, 1879, in Hays County, probably in Wimberley. In the June 1880 Census in Llano County, William and his wife were living next door to his brother Isaac in Llano County, Texas. In June 1980 the newlyweds had no children.

William Hickman Wimberley and his first wife Eller Leath probably had the following children before Eller's death in 1882-1883:

Her husband's second wife was Mollie L. Riggs.
