Benjamin Richard Craft, Sr, 1776-after 1860, married Sarah (Sallie) Becker, not Elizabeth Camper. Benjamin's brother, David Jonathan Craft married "Betsy" Camper. Dates for Benjamin's alleged marriage to Elizabeth and David's marriage to "Betsy" are the same.
Benjamin and Sarah were my paternal gg grandparents, and ended up in Craig's Creek section of Craig Co, Va.
There is quite a bit of documentation that the Craft and Camper families migrated together down the Sheandoah Valley of Va.
