How many times have I searched in vain for a clue and found it in another family that a daughter married into or a son married into.  There are many families that have married into the Sargent family.  To name a few we have information on:

BACON  = This family has a book published that documents the line back to Charlegmane.

HORTON= Another family documented back into England early in 1500's.

CHASE = Many researcher's with books and internet webpages.

COLBY = Every Colby in America is supposed to be traced by to Anthony!

WESTFALL= Just a few in PA but trying to find much more on this line.
