A few years ago, I was researching a family who lived in Illinois.  I knew that a teenage son had died, and I was trying to find his gravestone.  I knew where the family was living when he died (he died in the census year 1910), so of course that is where I began my search.  I could not find his grave though.  So, I found someone who could look for an obituary in the local newspaper.  In the obituary, it was mentioned that his body was to be transported back to where he was born.  So, I searched there for the grave, and found it!
