As someone who dabbled in geneology for a bit, even with the internet the best way to trace this information is microfilm of obituaries at the local historical society. Grand Forks may have this information due to it's distance from Adams. I'd try calling there and see what they have. If they do have that data, you can probably convince someone to take a look for you by sending them something nice from your local. Local brews are always a winner

Hell, I'm in Grand Forks 2-3 times a year (next visit mid-February). If you do find information I wouldn't put myself above being bribed with homemade goods.
