Kelsey is William and Lucy's sister, Bill's daughter, and Violette's stepdaughter, 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 daughter went through a divorce at one point and married Violette later, making Kelsey Violette's stepdaughter. She has made appearances in a few commons from before they became famous. She made her first appearance in "VIOLETTE1ST FAMILY GOES CRAZY IN OLIVE GARDEN!!!".
