I have added some info to James Tefft, between the source I added in support of his birth and additional info in Research Notes his details are correct. Tefft-169 is a duplicate and needs to be merged. The parent of Tefft-169 needs to be detached, as that John may not be a duplicate of Tefft-78 father. More research needed there, but for now the detachment gets you back in line with the sources.
