The Mattie Collection
 
Mattie Wilson founded and owned Wilson's from 1906 - 1941 with her husband Oscar.
 
After moving to Ephraim from Milwaukee, Mattie and Oscar Wilson along with their four sons (Harold, Orvis, Carl, and Hollis) opened a store featuring homemade ice cream and candy and so began “The Wilson Tradition.” Over the years they began serving food. The store itself was expanded to the north which allowed a third bedroom to be created upstairs. They also enclosed the porch seating area and helped with the construction of the flagstone floor which still exists today.
