I recommend, if you've not already done so, that you thoroughly check out the GenForum and Ancestry.com sites for Shamblin, Camblin, and several other spellings of the surname. My recollection of the matter is that these lines, at least some of them, came as indentured servants to Virginia, and that their origins, probably in France, remain unknown. Perhaps some newer information has come to light. I've certainly seen nothing, as yet, that connects them directly with the Tancarville line in Normandy or England, as you allege - if you know of a specific source for this information, please do inform everyone! This, if true, would be spectacular to learn!! We do have records for some Chamberlains or Chamberlins (and other spellings) in Shenandoah, VA - if you'd care to identify your Shamblins there (or other surname spellings you have listed there), I'd be happy to check it out versus my records here, and I'd be happy to correspond with you via Email.

, James B. Parker. Thank you for your posting. One key, as I've continued to stress with everyone in my postings, to solving some of these puzzles, is DNA testing. You didn't mention this in your article, but, working with Philip J. Chamberlain of the World Chamberlain Genealogical Society, this should be done for more of your Shamblin families, I do recommend.
