Well, I'll have a go re sorting out the KNIBBs as I have them within my K/NIBB/S database.
Samuel (son of Solomon) married first Jane MORGAN 1677.They had a son Samuel 1678 (d 17 Jan 1716 Henrico Co).Best evidence seems to be Jane died 1678 (though someone gave me 1688).Samuel then married a second time to Sarah BROWNE c1681 and they had 3 children, Solomon 1682, John 1690 and Thomas 1691 - I don't like the gap between 1682 and 1690!
Sarah BROWNE, brother Jeremiah,was the daughter of John BROWNE and Sarah Farrar (?) who later married a WOODSON.Her Will 4 Feb 1701 proved 1704 left property to her grandsons John and Solomon KNIBB.They were minors so a trust was set up for them.
I have a Sarah KNIBB daughter of John b1690 who married Robert WYNNE in N Carolina?
Where does your Sarah NIBB fit in?I have a note of her moving with husband John WYNN to Warren Co Georgia as you say and then marrying James HEFLIN after John's death.Can you please confirm/expand?
Is Nugent a County adjacent to Henrico?I've not come across the name Nugent before so far as I recall.
