I would like to throw out for dicussion anyone interested, that I have concluded there are two different sets of Ambrose Blackburns that migrated from Essex/Caroline County VA to Surry/Stokes County NC...It is well established that Ambrose Blackburn d. 1777 in SC and said to marry Elizabeth Jones and had sons Augustine and Ambrose, Jr who married Frances Halbert...It is also said that this Ambrose, Sr was the son of Elias Blackburn proven son of Cpt Christopher Blackburn who was in Old Rappahannock County, VA as early as 1666...it is also well established that both Ambrose, Sr and Jr had removed to SC in the 1770's...Newman Blackburn who made his will in Surry County, NC 1772 was witnessed by Ambrose Blackburn who deeded Newman 150 acres of land in 1771 in Surry County...this Ambrose also witnessed a will who I believe to be his 2nd wife Mary Cook's Father Robert C Cook's will in 1780 Surry County...I believe this Ambrose to be Ambrose, Jr who 1st married Hannah Ashley and both he and Newman to be the sons of Ambrose Blackburn who died 1754 in Caroline County, VA...Newman Blackburn was a defendant against William Dunlap and Co. in 1757 in Caroline County, VA...needless to say this is a confusing lineage with all the Ambrose's but seems reasonable and will appreciate discussion about this.
