Who would not want a world renowned brain surgeon as their 6th cousin?  Even 4 times removed?  I can confirm in my pedigree up to my 6th great grandfather, Moses Hitchcock (1717-1768). We’re Related goes three more generations with the MRCA being defined as PRIVATE (xxxx-xxxx)!  I may start with G’pa Moses and see if the next two generations pan out and then see if I can find the elusive and secret PRIVATE.  I do have a clue since the daughter on both lines carries the surname Filley.
