Brett Favre as my 9th cousin, once removed is a possibility, with a lot of research to complete verification on the pedigree chart Ancestry is proposing from the point of my 4 times great grandmother, Esther Clark to the MRCA, Joseph Dyer (1653-1704) which encompasses 4 generations.  At least the one PRIVATE in that string, Ancestry did not think was so secret in an early announcement and filled in the name of their proposal for my 9th great grandmother, Elizabeth Dyer (1680-1747).   Why they flipped to PRIVATE this time is a wonder.  This one goes on the TO DO list.
