Alfred Hitchcock is reported in # 369 as my 7th cousin, 3 times removed,  through our MRCA, Cicely Penny (1601-1683), the great grandmother of Moses Hitchcock (1717-1768), my 6th great grandfather and the furthest documented ancestor I have in that particular lineage.  Now, when I look at the connected lineages of cousin Alfred and myself, I see that Grandmother Cicely had two daughters : Hannah Chapin (1644-1719) and they each had a son, Nathaniel Hitchcock (1677-1761).  Coincidence?  I think not.  Failure to notice the trees are identical?  I think so.  It appears the MRCA is really Nathaniel Hitchcock, the father of Moses.   So, now I have a doable TO DO item!  And I do not need to fear Vertigo or the Birds!
