Sand Ridge in Grundy County

A couple posts ago I mentioned that Joseph Kallis, uncle to Dorothy Nelson Reimel Behnke, was buried in Sand Ridge. According to email exchanges with someone from Coal City Library she mentioned that there was a Sand Ridge in southern Illinois, but had not heard of a Sand Ridge in that area. In an unrelated search, I Googled "Towns in Grundy County." A search result showed a website that named the towns in Grundy County. One of the towns listed was Sand Ridge. I thought this may be a mistake, since I was told that Sand Ridge is in another county. So I Googled some more, "Sand Ridge in Grundy County Illinois." I found a map of Sand Ridge. It is located between Morris and Minooka, on the way to Joliet. I emailed the contact in Coal City, to give her the good news, and she gave me the email adress to someone at the Morris Library. Of course I have emailed this person. Praying to receive a positive answer with information about Frank Kallis and/or Lena Selinger.
According to Wikipedia Sand Ridge is unincorporated, and is in Aux Sable Township. It looks like there is not a cemetery called Sand Ridge Cemetery. The cemeteries listed are Aux Sable, Dresden and Saint Mary's. Details here.
I also put up a message on Ancestry.com asking about Sand Ridge. I received a reply. The messager says that there is a transcript of Aux Sable Cemetery available at Morris Library. I am not putting up all my bets on Frank and Lena being buried in Sand Ridge or the area. But this may look like a good lead, until I can find a yea or nay on this angle.
