Hi
I have just come across this so don't know if you have your answer but I have information regarding a John Wardell and his parents, grandparents etc. I have his forward tree and info on sibling and parentage. John Wardell and Eleanor Briggs did not have a child called Frederick and his son John born 1763 did not have a child called Frederick so I think this must be a different branch of the Wardell family. This line tend to use the same names from generation to generation as was the custom and Frederick is not a name that features anywhere in this line.
kind regards
