Ellerie Rollins grew up accustomed to being on the move, attending about 10 different schools by the time she graduated high school. Her dad worked as a corrections officer for the State of New York for 25 years, while her mom worked as a nurse and later became a nurse practitioner. While Rollins was an only child, her family was sprawling as her parents came from big families with lots of siblings, so the Rollins trio moved around various parts of upstate New York to keep close with the extended family and support as needed.
