Mary S. Snow, 68 of Wilmington, passed away surrounded by her family on Wednesday, December 23, 2020 at her residence. Mary was born in Philadelphia, PA, the daughter of Emilia (Zapotichna) and the late Michael Szulak. She was a retired nanny and public relations assistant, and loved reading, talking over coffee, and spending time with her family and her best friend of over 50 years, Peggy. Although she ultimately moved to Delaware, the Northern Liberties of Philadelphia was always near and dear to her heart. Mary is survived by her husband Rodger; her daughters Natalie and Dan Riffle; Christine Snow; Lindsay and Stuart Mundth; her four grandchildren Felicity, Emilia, and Jacob Riffle, and Margot Mundth; her mother; and her brother Michael Szulak. Funeral services will be held privately. In lieu of flowers, the family requests that you make a donation in Mary Snow's name to the American Lung Association at Lung.org.
