John, first you're going to need to find out what cemetery they're in. You can get that info from Grant County Genealogical Society for $3. Details are online at http://www.rootsweb.com/~wigrant/gcgensoc.htm#search

Next you're going to have to find someone local to take the pictures for you. If you're not familiar with "Random Acts of Genealogical Kindness" then let me introduce you. It's a wonderful group of volunteers. http://www.raogk.org/ Follow the links and read all the do's and don'ts so that you have a positive experience, like mine have been.

And you're in luck, Grant County has a volunteer for picture taking.

Good luck!
Robin
