The Michigan 100

I am nearing the end of my Twitter entries of #100over100: Michigan companies over 100 years old.  Several furniture manufacturers, five funeral homes, five hardware stores, six jewelry stores and seven shoe stores!  I didn't realize it when I started, but there are exactly 100 Michigan companies on my list of  businesses over 100 years old that I can verify.  I do have several more names, but cannot find websites, newspaper articles or other confirmation that they are still in business.  So next week (after we hit the 100 mark) I will post the full list on my blog and if anyone knows of Michigan companies that have been in continuous operation for over 100 years and are not on the list, PLEASE LET ME KNOW!
