Six parents and two wives. I have added the info from the DAR onto his profile. No evidence of a wife named Jane.
The mess with the parents does not match Find a Grave https://www.findagrave.com/memorial/83627269/john-boyd-robinson which lists his parents as
Nathaniel Nicholas Robinson 1723–1792
Mary Elizabeth May Robinson 1731–1782
Any assistance would be appreciated. John needs to be cleaned up along with wife and MPd if possible. I will help, but still researching.
