Well, it looks like Ancestry was not satisfied with nailing me with politicians!  I can only verify back to my 6 times great grandmother, Dinah Harris (1702-1796).  Ancestry claims Justin and my MRCA is Elnathan Tew (1644-1711) who would be my 8 times great grandmother.  This would be an investigation task, except that I also looked at the pedigree they provided for Justin.   It appears that his 7 times great grandfather, Michael Spencer (1725-1726) was able to father his 6 times great grandfather, George, in 1752, although he had been dead for 26 years.  AND HE WAS ONE YEAR OLD WHEN HE DIED.  Not sure where this tree came from.  Not sure I want to know.  Pretty sure it has been cloned a great number of times without anyone saying WHAT THE HECK!
