David Daniel WARNER - Names are being used incorrectly

I’m not sure if Anne is Anna or Anna is Anne Boynton.
David Daniel is used and Daniel David is used. I have also seen David and Daniel used in referenceing the same person.
They were married June 12 1744
Had 3 Children: Mary died at 3 mo’s, Lydia died young and Johnathan
Was orphaned at 6 years old.
