William Blake is reported to be my 5th cousin, six time removed, through MRCA William Lane (1580-1654), the proposed grandfather of Hannah Baker (1638-1717), my 8 times great grandmother and the furthest documented ancestor I have in that lineage.  So, added to the TO DO list from yesterday, I need two more generations to prove out in Jolly Old England.   I had better start saving for a long research trip!
