Go to www.familysearch.org
- they have transcripted Michigan death records 1921- 1952 "Michigan Death Certificates" and that will give you the exact dates of the deaths. That will make it much easier to locate the obits. The St. Clair Co. Library will look them up for a fee, or I might be able to get them the next time I'm up that way.
Check also the Macomb Co. genweb site where many obits are indexed. See what you find out and let me know.
