Lonnie Pertridge is a pre-made Sim who lives in Hidden Springs. She lives with her two "adorable" daughters, Astrid and Eunice, (who, in fact, are respectively inappropriate and evil) and with her stepdaughter Ella Carlisle, whom she dislikes. Ella is listed as her daughter in her family tree, but is her stepdaughter according to the family's bio. The family bio also states that Lonnie moved in with her two daughters in Hidden Springs and was annoyed by having to take Ella with her, essentially considering the latter a domestic. She is a very ambitious woman whose fondest wish is to see her dear daughters marry some rich, "royal" heir, such as Sebastian Vanderburg, son of two "leaders of the free world."
Lonnie and her family are thought to be parodies of the tale of Cinderella: Lonnie takes the role of the shrewish stepmother, Lady Tremaine, who only wants to marry her daughters to the prince, and who meanly exploits her goodhearted stepdaughter as a maid.
Lonnie is acquaintances with Renauld Vanderburg and enemies with Catarina Vanderburg. Her relationship with Catarina Vanderburg, the mother of the "prince" may not help her when it comes to marrying her daughters to the prince.
