There are a lot of questions here.
Her first husband is said to have died about 1797 in Campbell, Virginia.
Anne died in Albemarle in 1816
Yet her marriage to Benjamin is said to be in 1782 in Bedford
The kids were all born in Bedford, Virginia before the death of the first husband.
Benjamin dies in 1850 in Tennessee
There is some conflation happening here but with who is not exactly clear. Confirmation of sources and more research is needed. Have you contacted the PM's of the profiles in question to get some feedback? I would start there. Also the first husband, Christopher, is an orphaned profile, no reason why you could not do some work on that profile and see where it goes.
