Crittendens, Cruttendens, or Chittendens?????

I think somewhere I've given the scoop about the 6 or 7 more or less ancient Leete or Leet lines in North America that are derived from John of Eversden.  One of these lines is Isaac Leet, who immigrated to Hunterdon, NJ in 1686 or so.  In family trees and genealogy his line has often been mixed into and confused with the Gov William Leete line.  It's been a trial to pull all apart.  My question here involves the ... and this is really the question: involves the Crittendens, Cruttendens, and or Chittendens.  I've seen these three names and more given to the same person!  Can anyone help out.  It seems that the Cruttenden name seemed to morph to Crittenden, and yet the Isaac Leet line is full of Crittendens, from Virginia, not Guilford.  Help!
