We share the same great grandparents in Thomas Lyncoln Clarke, l and his wife Lady Joane Katherine Clarke (Northos). Of the top 513 historical genius that Geni.com projects has I find myself related to 286 of them. Christopher was not on this list because he is not historical but he'd be near the top. He shares my great grandfather with these other genius' John Locke, Philosopher, 170 IQ, William Henry Channing, 160 IQ, and Walter Elias Disney, 140 IQ. Thomas Lyncoln Clarke's great grandson was John Clark, of Jamestown, Mayflower Pilot my 9th great grandfather. Nice company to be in.
