This line was provided by John Mutch of Idaho and is based on information contained in the 1929 Genealogy of the Mutch Family by James Robert Mutch where he is listed as B1. I have modified some of the data to match what is available in IGI.
John adds David Mutch is the ancestor of all the Mutch families of Wisconsin State, USA as well as large numbers of the name in other parts of the US and a few in the Province of Manitoba, Canada, and three families in Aberdeenshire, Scotland. All of the family of his son John emigrated to or near Hillsboro, Wisconsin, between the years 1850 and 1860.
