"**** ******** ***** is of Swiss, German, Dutch, French, Scotch, Irish, Welsh and English ancestry, which has been traced back several centuries on many different lines, and on one line back to Adam and Eve, naming the direct ancestor in every generation back to the Garden of Eden."
I was relieved to find that the surname of my interest is not connected to the supposed Adam and Eve line — which wasn't even listed in detail, by the way — but I'm still going to use what I found as a road map. Thankfully, the info for the family I'm researching appears to be plausible.
