Thanks, Jacob, for your reply.
"Notes for WILLIAM CLARK:
William's will N.C. Hd. New Castle. Feb. 13, 1783. Feb. 25, 1783. L., 311, Sister, Margaret; Allice, Ann and Elizabeth Clark, daughters of brother, John Clark, dec'd.; Richard, William and John Clark, sons of brother, John Clark, dec'd. Exc. brother-in-law, William Armor."
Yes, your material does show an Armor/Armour/Clark connection of two families of the name.
But the children of William Clark's brother John Clark mentioned in William Clark's will don't match any of the sets of Clark orphans in the court records, do they?
Jake, in the will: Allice, Ann, Elizabeth, Richard, William, & John, children of a John Clark, as you write.
But the orphans court records show:
(1) John, George, Thomas, & Mary, orphans of a John Clark
(2) James, Mary, Jane, & David, orphans of a John Clark
and (3) Henry Clark, orphan of a John Clark.
So instead of possibly three, there seem to be FOUR different John Clarks, leaving behind orphans. ;-)
