Maisie is Vivian/Niamh’s biological little sister. She is conceived during the voyage to America and born in New York in 1927. As a child, Niamh is responsible for taking care of her little sister and forms a strong bond with her. In 1929, a house fire kills her father and brothers. The family’s neighbors, the Schatzmans, lie to Niamh and tell her that the fire killed Maisie, too—but they actually adopt her and raise her as their daughter. Maisie moves to upstate New York, marries and has children and grandchildren. She dies just months before Vivian discovers that she survived the fire. Unlike Vivian/Niamh, Maisie has blonde hair.
