Arkansas, but soon moved across the Mississippi River to Commerce in the Mississippi Delta, near Tunica and Robinsonville. They lived on the Abbay & Leatherman Plantation. Julia's new husband was 24 years her junior. Robert was remembered by some residents as "Little Robert Dusty", but he was registered at Tunica's Indian Creek School as Robert Spencer. In the 1920 census, he is listed as Robert Spencer, living in Lucas, Arkansas, with Will and Julia Willis. Robert was at school in 1924 and 1927. The quality of his signature on his marriage certificate suggests that he was relatively well educated for a man of his background. A school friend, Willie Coffee, who was interviewed and filmed in later life, recalled that as a youth Robert was already noted for playing the harmonica and jaw harp. Coffee recalled that Robert was absent for long periods, which suggests that he may have been living and studying in Memphis. Once Julia informed Robert about his biological father, Robert adopted the surname Johnson, using it on the certificate of his marriage to sixteen-year-old Virginia Travis in February 1929. She died in childbirth shortly after. Surviving relatives of Virginia told the blues researcher Robert "Mack" McCormick that this was a divine punishment for Robert's decision to sing secular songs, known as "selling your soul to the Devil". McCormick believed that Johnson himself accepted the phrase as a description of his resolve to abandon the settled life of a husband and farmer to become a full-time blues musician. Around this time, the blues musician Son House moved to Robinsonville, where his musical partner Willie Brown lived. Late in life, House remembered Johnson as a "little boy" who was a competent harmonica player but an embarrassingly bad guitarist. Soon after, Johnson left Robinsonville for the area around Martinsville, close to his birthplace, possibly searching for his natural father. Here he perfected the guitar style of House and learned other styles from Isaiah "Ike" Zimmerman. Zimmerman was rumored to have learned supernaturally to play guitar by visiting graveyards at midnight. When Johnson next appeared in Robinsonville, he seemed to have miraculously acquired a guitar technique. House was interviewed at a time when the legend of Johnson's pact with the devil was well known among blues researchers. He was asked whether he attributed Johnson's technique to this pact, and his equivocal answers have been taken as confirmation. While living in
