I won't be able to identify any of the pictures, but I think I can get you in touch with a member or two of the Boerner Family from Grant County. I have a message to a contact of mine, so I will circle back when I hear back.
If you haven't already checked it out, www.findagrave.com
has some records for grave sites and sometimes has photos. I just searched on the Boerner's in Grant County and there are a few that have photos.
There is also a Boerner Family cemetary that was in the local news recently. Just do a search on Boerner Family Cemetary, Grant County Minnesota. Here is a link to one article that was written. It's been in most of the regional papers and is still under investigation.http://www.twincities.com/localnews/ci_22357094/minnesota-pi...
