The youngest member of the Hartley family, she is one of the subjects of her mother's family blog The Hartley Hooligans. The blog documents the Hartley's lives as they manage her and her sister's microcephaly.
Her mother, Gwen, began The Hartley Hooligans in 2011.
Both she and her older sister, Claire, have microcephaly caused by an Asparagine Synthetase Deficiency. The condition is genetic, inherited recessively through both her mother and father.
Her mother, Gwen, is a blogger, while her father, Scott, is a glass blower. She has two older siblings, a brother named Cal and a sister named Claire.
Like Lucy Devine, she is the daughter of a popular family blogger.
