How many wives did muddy waters have?

I have found sources that say McKinley "Muddy Waters" Morganfield married 4-5 women, though I have found 3 names. He had six children, none with his wives; in addition to other step-children that he helped to raise. While Muddy tried to be the best family man that he could be, most sources say that he always had women and several children born outside of his marriages.

Wives:

Mabel Berry (1932-1935/ left when Muddy's first child was born to another woman (Leola Spain - whom Muddy never married)

Sallie Ann

Geneva Wade (19?? - 1973/married until Geneva's death)

Marva Jean Brooks (1976 - 1983/married until Muddy's death)
