Four new Dutchesses of Pella have joined the group, and they’ll begin rehearsing soon. Amy Van Haaften, steering committee member who has worked with the group for the last several years says the group of 16 students participate during their freshman, sophomore and junior years of high school. The incoming freshman this year are Sarah DeWulf and Claire DeVos from Pella High School. Joining the group from Pella Christian are Jessie Voss and Rachel Vermeer.
