What are the motifs in The River Niger by Joseph A. Walker?

A recurring idea is concerned with the role of women in the African-American family, particularly in terms of how they treat their men. All the women in the play—Grandma, Mattie, Ann, and Gail—are presented in a positive light because they are completely loving, supportive, and non-judgmental toward their men. Grandma seems to be a role model in her absolute idealization of her deceased husband, asserting, "my man was a king."
