I have the Ancestry.com subscription that gives me access to census records, but since I don't know where they were in Minnesota I didn't know where to start. The 1900 and 1910 census records in Ancestry are not indexed so that would mean going through the whole state name by name. If you have access to an index, then maybe you could find it. If you don't then I wouldn't bother. WAY too much work! I will see if I can find a death record for Mary Kronick that would at least give me a maiden name. I'm still trying to track down a death date for John Kronick. My plan is to go to the courthouse tomorrow, so I will look up Emma for you and let you know what I find.
