Miles of Fairbairns

Think I've found David and Jane (HERD) FAIRBAIRN's dtr Jane in the States as well.
On the Waushara County, Wisconsin GenWeb site there are some marriages transcribed from the Wautoma Courthouse records, including an 1854 marriage of a Jane FAIRBAIRN and a Joseph PROCTOR. Census data shows that Jane was born Scotland c 1824, AND they lived in Mt Morris, Waushara County, which is also where David and Jane were to be found at one stage.
Dtr Elvira married a Joseph MILES and lived Dale, Cottonwood, Minnesota, then Garfield, Washington State.
Anyone got any obits to prove these connections?
Jane appears to have disappeared between 1880 (Dale, Cottonwood, Minnesota living with dtr and son-in-law) and 1900. I've not found Alvira (MILES) beyond 1900 (River, Garfield Co, Washington) as yet.
