In working on an article for the Ancestry.com blog, I needed to do some neglected followup work on a cousin who died in Minnesota. It had been a while since I had used the online Minnesota Death Certificates Index.
After I found the reference I needed, I went back and "wasted" some time playing with the "mother's maiden name" box for several last names I have. A nice feature of this site; I found several relatives who had been "lost" simply by entering in their mother's maiden names and a few I had NEVER thought to look for in Minnesota. Too bad they didn't index father's last name as that would have caught a few more, probably. But I'm not complaining.
