Robert Boyle, the father of modern chemistry, is supposed to be my 3rd cousin, 11 times removed (now that makes us close!).  The pedigree from Ancestry goes from my 6th great grandfather, Moses Hitchcock (1717-1768) to two levels of PRIVATE — male, then female, to reach Samuel Chapman.  The father of Grandpa Moses was previously identified as Nathaniel Hitchcock (1677-1761), so I do not know why it is now a secret.  And then the PRIVATE leap to his maternal grandfather, Samuel, leaves questions. But, the line to the proposed MRCA, Cecilia Nevill (1488-1573) is still not clean with linkage child of Cecilia to the maternal grandfather of Samuel being defined as PRIVATE.  A person born in the EARLY 16th century being classed as PRIVATE is concerning.  It is like saying, “we don’t know, but there should be a person here to connect it all”
