Karen:You really need to be in touch with Bartina Peoples. I know that she has the Briggs line way back.I just haven't gotten all of it and put it into my files. I can tell you the Jacob Briggs' father was Elkanah Eland Briggs and his mother was Elizabeth Harris.Do you have any information on the children of Jacob and Caleba Duck. I would like to have marriages if known and full birth and death dates. Bartina may be reached thru email@example.com.Meanwhile I will dig into my records and see what else I can find on the Briggs. My special interest are William and Sarah Cullifer Duck, Caleba's father and mother.Keep in touch.
