Another location named for my ancestors

The Meharry family line, of which I am descended from Alexander "Red" Meharry III (1763-1813), left their mark in a few place names in western Indiana.  I've known about the Meharry Cemetery in Wingate, Indiana, where many of this family is buried, for a while now.  Since I'm actively researching this family, I've been looking around recently at other history references that deal with this part of the state.  Here's a fun tidbit from the History of Montgomery County (published in 1881) about another place that carries the family name:

Meharry Grove
If there is one spot in Montgomery county more celebrated than another (and there certainly is), that spot is Meharry Grove.  Located on Coal creek, one and a half miles north of Pleasant Hill, a high and beautifully shaded place, it has been the favorite campground for over thirty years.  The grounds contain about forty acres, a large number of seats are provided, and water is plentiful.  Here it has not been an uncommon occurrence for thousands of happy faces to congregate.  The eminent divines, Cyrus Nutt, Pres. Berry, Bishop Bowman, Dr. Brenton, have preached to immense audiences.  Here was held a mammoth temperance rally about 1875, addressed by the "Broad Ax," or M. D. Chance.  Here too, have ex-Gov. Col. Robert Hawley, of Centennial fame, Gov. S. M. Cullom, of Illinois, Hon. G. S. Orth, Judge T. F. Davidson, and other renowned statesmen, proclaimed American principles to vast concourses of people.  In all these gatherings the prevailing characteristic has been good order and universal enjoyment.

There's a 1916 obituary for Charles W. Meharry published in the Crawfordsville Review that mentions the "widely known Meharry family of Western Indiana" held a number of annual family reunions at Meharry's Grove, placing it on the border between Montgomery and Fountain Counties, which would place it on the western edge of Montgomery County.  But, I have yet to find a map that shows this location more precisely.  Looking at current satellite images of the area, there are a few areas surrounding Coal Creek that look like they have not been farmed.  I suspect that Meharry Grove was a parcel of farm land that was once owned by the family, and that Meharry Grove was an unofficial name for the farm.  But again, I don't have any proof of this yet.
