There appears to be duplicate Kathryn Napiers married to Brocks, both attached to the same father. One's husband is called George and other's husband is called Frederick. Genealogist Clarence C. Brock, in his book called 'Frederick Brock, 1719-1807, His American Family', says nothing is known of Frederick wife's ancestry.
All the "sources" on this Kathryn just go to Rootsweb trees with no primary sources. Who, if anyone, did Kathyn Napier marry? Is she just attached to these Brocks to give them a "good" ancestry? (read: royal). What is the truth of the matter?
