Mercedes Piper is the second daughter born to James and Materia. While Materia could not love or bond with Kathleen, she discovers that she is able to love Mercedes without even trying.

Mercedes is similar to her mother in her devotion to Catholicism. She prays and says her rosary often, even using other objects as a way to say the rosary. As a young woman, her faith is tested by Frances' wild phase and subsequent pregnancy. At times she seems to trust in God more than her own common sense, as evidenced by her deception of Frances when she has her son.
