She was fiercely loyal to her family and friends. She raised two sons, with her husband Sanford Noah Katz, who preceded her in death in February of 2024. She was incredibly proud of her family, son Daniel Katz of New York and his wife Meg Parsont and son Andy Katz of Newport, RI, and his wife Denise Padilla.
