Metamorphosis

I am going to have to do more research. Were California and Nevada even states by the time the Civil war happened? I know Michigan was as I remember it being in the war in my history class I took. Also from my understanding yankee was specific to the North-eastern states, but I could be wrong as it is information from my husband and I don't know what his sources were, but he is generally very good about getting reliable sources. *Shrugs*
