Diamond Grove

In doing research about the Civil War in the area of Newton and Jasper counties, I have occasionally run into references to Diamond Grove. At first, I assumed that Diamond Grove was just a precursor to or another name for present-day Diamond, which did not exist at the time of the Civil War. There's some truth to this assumption, but it's not entirely true. While present-day Diamond did borrow its name from Diamond Grove and is located in the same general vicinity as the earlier community, it is not located in the precise same place.
Diamond Grove was north and west of present-day Diamond or due north of the George Washington Carver Birthplace. In fact, there's a Diamond Grove Prairie Conservation Area just a couple of miles north of the birthplace, and still farther north (on FF Highway or Joplin's East 32nd Street) there is a Diamond Grove Christian Church.
If there was an actual community or crossroads store during the Civil War at a place called Diamond Grove (and I assume there was), I have not, however, been able to determine exactly where it was. All I know is that it was not where present-day Diamond is. If anyone knows the precise location where the community of Diamond Grove was, please let me know.
