I'm confused about the connection between "Blue Island Families" and Staunton, Macoupin County, Illinois. Anyway, here is one connection for you from the Illinois State Archives. They also had one marriage but it was not in Staunton. Seems there were quite a few Teuferts north of Chicago in Evanston, Niles, etc. This is Mary's death info. You can go to the Archives site and find info on how to order this certificate. TEUFERT MARY F/W Y-82 0012646 1935-03-24 MACOUPIN STAUNTON Joan in Illinois
