Parish Grove Township was one of the county's original three created in 1840. The grove for which it is named grew close to the township's southeastern corner, near what is now the intersection of county roads 400 West and 300 South. It originally covered about and contained an abundant variety of trees, including oaks, walnuts, hickory, dogwood, haw, paw paw, sycamore, quaking ash, ironwood, water beach, elm, linn, poplar, ash, sassafras, locust, etc. As late as 1924 there were 37 varieties growing in the grove. Parish Grove was home to a group of local
Pottawatomie Indians led by Chief Parish (real name Pierre Moran), the son of French trader Constant Moran and a
Kickapoo woman. Parish died
circa 1826 and is buried in the grove, though the grave is unmarked. ==Geography==
