Williams's parents, Elonzo Huble "Lon" Williams and Jessie Lillybelle "Lillie" Skipper married on November 12, 1916. Hank Williams was of English-American ancestry. Elonzo Williams worked as an engineer for the railroads of the W.T. Smith lumber company. He was drafted during World War I, serving from July 1918 until June 1919. He was severely injured after falling from a truck, breaking his collarbone and sustaining a severe hit to the head. After his return, the family's first child, Irene, was born on August 8, 1922. Another son of theirs died shortly after birth. Their third child, Hiram, was born on September 17, 1923, in Mount Olive. Since Elonzo Williams was a Mason, and his wife was a member of Order of the Eastern Star the child was named after Hiram I of Tyre (one of the three founders of the Masons, according to Masonic legend), but his name was misspelled as "Hiriam" on his birth certificate.
