Her name is Catherine A Berkeley, Berkley, Barkley, etc. She is the sister of Mary Elizabeth Hackley. They came to Lafayette Co, MO from Rappahannock Co, VA after their father died in 1855. There is a child listed under Catherine in the 1860 census of Dover, Lafayette Co, MO in the Martin Hackley household. Where did you get Willett?? Her sister, Susan F Berkley married John R Willett in Rappahannock Co, VA in 1843. Is this a coincidence?

I have this family listed in my family tree Ellzey Family Tree with Wheeler Roots.
