William Rockefeller as 6th cousin, 4 times removed would be the perfect example of the family black sheep!  Everyone wants this type of scoundrel in the family.  And it does not hurt that his two sons founded Standard Oil!  The pedigree provided leaves two undocumented generations for me to get to the MRCA, Elizabeth Starkey (1614-1684).  So, the TO DO list expands!  The bio blurb above from wikipedia and the picture of cousin William is that of his son, William, Jr.   William, Sr. was NOT one of the founders of Standard Oil, but was an “botanic physician” that sold elixirs.  Your basic snake oil peddler.  His full bio really does earn him the Black Sheep mantle.  The pedigree for William shows him as William, Sr., the son of Lucy Avery and Godfrey Lewis Rockefeller.  It is through the Avery line that William is attached.  Obviously, William, Jr. does appear in the same line, just one generation later, but he is not the one reported by We’re Related.
