Casnovia is believed to be the only place on Earth with that name, now or at any time in the past. The name is a distortion of the settlement's original name, Casanova Town, founded by Jedediah Craw in 1852. Craw was a Mormon with four wives, all teenagers at the time of his arrival in the area. The name Casanova Town was most likely bestowed on Craw's compound by neighbors, as a reference to his polygamous lifestyle. The settlement grew along what is now Ball Creek, and took the name Casnovia in 1861. (From Wikipedia, the free encyclopedia)
