The Hansen family business, Racine, Wisconsin.
Bothilda Marie Hansen married Carl William Johnson, whose father was John Johnson, AKA Hans Hansen, and the junction of the 2 families really made it Hansen & Hansen (M.C. stands for Mads Christian Hansen).
Mary S. Jensen Johnson was the mother of Carl William Johnson, of Kenosha, Wisconsin.
