Keeley Williams was born on Feb. 14, 2003. She is Jason's oldest daughter and his firstborn child with his previous wife, Jessica Ussery. Keeley is musical just like her dad, and even plays guitar. Her musical taste is less country and more rock and roll, though. Keeley and her sister Kendyl are also very close with their stepmom, Brittany, which Brittany opened up about to Us Weekly in May 2020. "I do love the fact that they're a little bit older because it's so fun. I really am starting to relate to them, especially the older one. She's going through things now that I can really relate to."
