The Father of Erik Knutson is Knut Simonson - my fater David Smith Wyckoff gave me a published book that goes back to 800 AD. Pieter Claesen Wyckoff was my 10th Great Grandfather. It is a very interesting read going back to Kings in the 800's.....The Battle of Hastings where my 27th GGF lost his life..... It goes back all the way to Bhorn II Eriksson (The Old) King of Svithjod.
