Crago Genetealogical Family Tree      
       
  "Adam", his Unknown descendants, and their dates are all speculation      
   Dotted Line Relationships cannot be determined accurately in time. "Adam"? (1608?)      
   Average Mutation Rate is approximately = 0.001974           NOTE --    
   Generation Gap (in Years) to Adam =  31.8 Unknown? (1633?) Unknown? (1639?)   Genetically, we    
   One or more mutations have occurred in each dotted red box     hve found three

Notes: Kit 169609's lineage is mostly English -- Richard (1875) was the first to immigrate to America, about 1900.  All other lines are American, as far as documentation goes.
Marker 447 seems to define a major branch of the Crago family tree, covering most present-day American Crago's and Craigo's.
Marker 450 seems to further define two large branches of the Crago family tree in America.
Volunteer 17752 appears to have a mutation on marker 447 back to our assumed ancestral value of 25.  His paper trail is convincing that Isaac (1825/6) is a brother of John W (1819).
Seven of the sibling relationships (shown by solid lines) are well-documented on paper.  Two are confirmed by DNA -- see Markers 391 and 617. 
?  = These are marker values we should try to obtain. We expect 450 = 8 and 617 = 12. Markers 481 and 492 are not predictable for Kit 194292.
