Betty, I personally tend to doubt the connection of Samuel Flake of Anson to New York. Not only have I never seen any evidence to connect him to New York (other than accounts in various family histories), but considering the references to a Samuel Flake in the records of the Granville District of North Carolina (which is on the border area of North Carolina and Virginia and in the vicinity of where Robert Flake of Isle of Wight County lived) prior to the date of when Samuel Flake's name first appears in the extant records of Anson County, I've long tended to believe it is more likely that Samuel of Anson is the Samuel Flake of the Granville District and somehow connected to the other Flakes in this region. Of course, Robert Flake having died intestate hasn't helped matters. <grin> Still, the migration pattern would make sense and along with the Eastern Shore of Maryland this general region of Virginia and North Carolina, were among the areas which provided the most origins of many of the early settlers of Anson County, including the Hooker family (Bertie and Chowan counties, NC) into which Samuel's daughter Delilah Flake married into.
However, regrettably, I've never gotten around to exploring the possibility in depth .
