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.

An email from Beth Collier dated 8th November 1999 on the Mutch Surname Board at Ancestory.com gives David's parents as David + Elpset Davidson. I have been unable to contact Beth to confirm the details.

I have since come across the information posted on GenCircles by Leslie Gerard Hay under the Gerard Family Tree. I have so far been unable to contact Leslie to confirm his data
