Ellen was a champion swimmer who joined Dophin Swimming Club in Mayfield on the northside of Cork city when she was nine years old. In a post on Facebook, the club said that Ellen made a tremendous impression on everyone she met. “Ellen swam through life with grace, strength and passion. "Your smile and your drive will never be forgotten. Our deepest condolences to all the Cassidy’s family and friends.” Ellen was very much loved at the club not only for her talent in the water but for her kind and giving nature.
