I came across your article by accident and was pleasantly surprised. My grandfather was Ignatius Kirchman, one of the two founders of Kirchman Bros. My father, Hubert (Hub) Kirchman and his cousin Frank, son of the other founder (also named Frank) took over the business as partners after their fathers passed away. My father eventually sold his share to his cousin and we moved to CA. We still have some of the products (a toaster, gas BBQ and waffle iron) from the 1950s that have the "Kirchman Bros" emblem on them - and yes, they still work and are used regularly! The Kirchman family home is one of the historical Center Street homes (1315 Center St). Thank you so much for helping to preserve Bay City's history!
