Found the following information in a Northen Family Manuscript entitled "A Short History of the Northen Family in the United States," by E. E. Northen.(Note that the last name spelling is without an "r."It would appear that the original spelling, at least of a portion of the family was Northen rather than Northern).
Barbara Baker Northen's parents were George Northern and Margaret Jones.Her grandparents were William Northern and Abigail Minty.For other ancestors and family, please visit my Northern Family Genealogy web site at www.northern-family.com.
Incidentaly, George's brother, Peter Northern married a Jane Alderson.Perhaps she is a relative of yours.
