Winnie is a second-generation Irish American, with origins in counties Mayo and Leitram on her mother’s side and County Tyrone on her father’s side. She and her husband, Bill, who is a retired police force detective have one son, Patrick. They enjoy sharing their Irish traditions, which includes marching in the NYC Saint Patrick’s Day parade and hosting their annual Saint Patrick’s Day celebration. Winnie takes great pride in her Irish heritage and attributes her strong values and good sense of humor to her Irish upbringing. Winnie lives by a quote that her Irish grandmother taught her at a very young age: “If you’re going to help someone do it from your heart, and expect nothing in return. You will be surprised at the many blessings that come your way.” ♦
