The story

How Millgrove came to be

From Wikipedia’s history of Millgrove.

Read it all →

Millgrove was laid out in 1867 when Blackford County's first railroad came through the southern portion of the county. The community's post office opened February 25, 1868, and continued until March 31, 1955. An 1882 gazetteer, which listed the community as "Mill Grove", called the town "a place of 50 inhabitants". The gazetteer also listed a physician, justice, and railroad agent. During the 1880s, Millgrove had three general stores, a blacksmith shop, a sawmill, and a tile factory.
