Background: Huddie William Ledbetter  (January 20, 1888 - December 6, 1949) was an American folk and blues musician notable for his strong vocals, virtuosity on the twelve-string guitar, and the folk standards he introduced. He is best known as Lead Belly. Though many releases credit him as "Leadbelly", he himself wrote it as "Lead Belly", which is also the spelling on his tombstone and the spelling used by the Lead Belly Foundation.
Context: Lead Belly was born Huddie William Ledbetter on the Jeter Plantation near Mooringsport, Louisiana, on January 20, 1888 or 1889 (generally accepted to be the former). The 1900 United States Census lists "Hudy Ledbetter" as 12 years old, born January 1888, and the 1910 and 1930 censuses also give his age as corresponding to a birth in 1888. The 1940 census lists his age as 51, with information supplied by wife Martha. However, in April 1942, when Ledbetter filled out his World War II draft registration, he gave his birth date as January 23, 1889, and his birthplace as Freeport, Louisiana ("Shreveport"). His grave marker bears the date given on his draft registration.  Ledbetter was the younger of two children born to Wesley Ledbetter and Sallie Brown. The pronunciation of his name is purported to be "HYEW-dee" or "HUGH-dee." He can be heard pronouncing his name as "HUH-dee" on the track "Boll Weevil," from the Smithsonian Folkways album Lead Belly Sings for Children. His parents had cohabited for several years, but they legally married on February 26, 1888. When Huddie was five years old, the family settled in Bowie County, Texas.  The 1910 census of Harrison County, Texas, shows "Hudy" Ledbetter living next door to his parents with his first wife, Aletha "Lethe" Henderson. Aletha is registered as age 19 and married one year. Others say she was 15 when they married in 1908. It was in Texas that Ledbetter received his first instrument, an accordion, from his uncle Terrell. By his early twenties, having fathered at least two children, Ledbetter left home to make his living as a guitarist and occasional laborer. When Lead Belly was released from his last prison sentence, the United States was deep in the Great Depression, and jobs were very scarce. In September 1934, in need of regular work in order to avoid cancellation of his release from prison, Lead Belly asked John Lomax to take him on as a driver. For three months, he assisted the 67-year-old in his folk song collecting around the South (Alan Lomax was ill and did not accompany his father on this trip).
