James was the son of Samuel Henry Gaines, and husband of Laurel Laughlin (married about 1904).
In 1900, he was living in Kauffman, Texas. He worked with the Trio and/or Quartet Music Companies in Waco, Texas.
The family moved to Tennessee by World War I, when Gaines was drafted for military service. After the war, he ran a music publishing company in Memphis, Tennessee.
