There are numerous towns and villages that have diminished and disappeared in Michigan; the ones you usually hear about are in mid-to-northern Michigan. The Jackson County village of Leoni may have shrunk down to be a shadow of what it once was, and some maps don t even list it any more, but it still hangs in there.
Leoni sits in the township of the same name, about halfway between Jackson & Grass Lake at the intersection of East Michigan Avenue and Portage Road.
According to geneologytrails.com, in 1836 William Jackson came through Leoni looking for wild land...Leoni appeared to him a second garden of Eden...in October, 1838, he chose it for his home, and engaged in the sale of dry-goods, groceries, Sapington s ague-pills, and Peleg White s salve, and subsequently sold Pratt s pills and Lond s ointment.
