Noah Porter-Benson (biological grandson)
Sheila Porter is the biological grandmother of Noah Porter-Benson and the mother of late Ellie Porter.
While investigating a case, Trevor Langan approached Olivia in her office, telling her that Noah has a grandmother and that she is filing for custody. Olivia, clearly distraught, asks him to leave. Eventually, Sheila comes to Olivia‘s apartment and confirms who she is.
