Thanks to all the great links from this list, I checked out information on the Bozeman Trail at http://www.wavecom.net/philkearny/btcaphist.htm . The article is specifically mentions "In 1864 four large trains went over the trail and established the route from Casper to where it intersected the Bridger Trail west of Billings." We know that my husband's great-grandmother, Mary M. ZIEGLER arrived in Virginia City, Montana, 7/10/1864, traveling via the "Bozeman Route". It seems possible that she may have been in one of these wagon trains. Does anyone know if information regarding the travelers in these trains exists?
