She is Herman's spoiled but sweet girl and Max daughter. As Cecilia, she loves to cook and is very good at it. Many of her requests involve testing her inventions. As part of Alvarna's wealthy De Sainte-Coquille family, Rosalind's requests initially offer a lot of money.
Rosalind also shares this interest about clothes with Julia. When Rosalind cannot be found inside her house, she can be found hanging out with Julia and Dorothy inside the church (Tuesdays and Thursdays) or with Julia outside the bathhouse.
