You have a several more duplications than just Benedict, Abigail and Phillip-- John James Crews / John or James Crews then John Crews/ John James Crew II in what little I can see…
As @rzamor1 says go thru 1st and Manual Merge all your duplicate people BUT make sure that you pick the person with the most /correct info or name you want to keep as the primary then merge into the other— so that means you will have to merge Abigail then turn around and merge her again…
