Well I don't know about the first Chew but I have learned of a knight(1030-1106) who may have been part of William the Conqueror's army. I have no name and neither with his son, but with his grandson named Alvred (1100-1170).
Now the 1st Knight lived back in Normandy, France, and died in Somerset, England but the son was born in Devon, England. Apparently, the family was given title and land.
I can trace their descendants to John Chew who immigrated to the States in 1622 and all the way up to Leah Chew (1839-1867) whom married into my fall of Patterson's.
But I would also appreciate any more information on this lineage.
