Trish Minniver, played by Paula Wolfenden, is the mother of Mitzeee Minniver and Maxine Minniver, who arrives on her birthday to see her family. It is revealed that she has bitter feelings towards her niece "that she treated like a sister" Heidi Costello, this is because Trish used to date Carl Costello before he left her for Heidi. She appears to be using her daughter Mitzeee in her plan to make Carl and his family's life hell. Trish reappears at Christmas 2010 with Mitzeee and makes peace with Heidi and Carl, before befriending Myra McQueen. Trish encourages Heidi to be more accepting of her transgender son Jason Costello.
