Hi Carole,
Thanks for the reply. Yes, it's quite possible that Boone is a variation of something else - Bown(e) and Bown(e)s are suggested although they may be Scottish. Seary states that the name comes from the French place name Bohon. Can you suggest any Guernsey surnames that might have been corrupted to Boone?
Alternately, the name may have died out in Guernsey. Most settlement in Newfoundland was prior to 1815, particularly the period 1780-1815. Early instances of the Boone surname in Newfoundland suggest an even earlier arrival, possibly as early as 1723 or even 1625, so perhaps there were few or no Boones of the male line left by 1841+.
