Different mother and different wives.

I am doing simple clean up in the Mattox/Maddox tree and am not working on the Bollings

Can someone please look and make the disconnection/date changes if they are two different men? Surely they did not both die the same day with the same name and same father.
Did Colonel John Bolling, of Chestnut Grove have another wife?

Thank you--( I am on my way to the dentist :/ so I cannot resolve this easily right now but am bringing attention to it)
