Kelsey is William and Lucy's sister, Bill's stepdaughter, and Violette's daughter, as revealed in a recent fan mail video. While known, little was known about her background, and now that more is known, it is likely that Bill's stepdaughter went through a divorce at one point and married Violette later, making Kelsey Violette's daughter. She has made appearances in a few commons from before they became famous.
Her hair is blonde (as seen in commons).
- She was born on February 23, 1994.
