The Canterbury's in Illinois came here in 1823 from Kentucky, prior to that they came from Virginia, All Canterbury's in America are related. I have an extensive background for the family. There are some holes but it seems they came to America in 1638. Roger and Samuel I think they all stem from these men. Please call if you would like to discuss the family Harry Canterbury. The Missouri bunch left Illinois about 1855 or so and went to Burlington. I think that is your branch.
