To be a member of the Girls of '68, you have to be a girl, but you don't have to be 68.

In fact age is not a requirement at all. It enabled Stephanie Warnstadt, 9, to recently join the organization.

"My great-great-grandmother and my great-grandmother were members and my grandmother is a member," she explained. "I joined because I thought it important to pass on that tradition."

Tradition is part of the Girls of '68 focus. The group evolved from a birthday club formed in the 1890s. It was organized in 1932 by a group of Sioux City pioneer women and incorporated the next year with the simple purpose to promote, preserve and cherish the historical aspects of Sioux City.

Irene Jotzke was invited by a friend to join in 1973.

"At that time one of the requirements was to have lived in Sioux City for 50 years," she said. "That's been changed to five years now."

The organization meets monthly for a luncheon, brief business meeting and presentation. The group serves as custodians of French fur trader Theophile Bruguier's Cabin in Riverside Park, where monthly meetings are held in nice weather, explained Marvis Hendrickson, business agent of the club.

"Members provide conducted tours of the cabin for fourth grade students who are studying Sioux City history," she said. "Tours are also available by appointment."

Membership is on the rise, according to Hendrickson, due to those tours.

"We've had about a half dozen new members join recently," she said. "Many of them are retired teachers who brought their students to the cabin."

Other club officers are: President Gloria Klein; Vice President Jackie Warnstadt; Recording Secretary Sue Hinrichs; Treasurer Jean Braunger, Corresponding Secretary Virginia Pflanz and Financial Secretary Joyce Fredrickson.
