With the cooperation of several cousins, I am compiling a genealogy of the descendants of Thomas Collier, who came to Hingham, Mass. in 1635. One son stayed in Mass., the other, Moses (ca 1625-1684), moved to and died in Woodbridge, Middlesex County, NJ.
I have been able to compile a list of about 380 descendants (and spouses) of Moses, many of whom changed the spelling of the surname to Collyer or Colyer not later than 1740-1750. If anyone has "Collyer, Colyer, or Collier" ancestors from Middlesex, Somerset, Morris or Sussex County, NJ, we may be able to make a connection.
Likely names in the 1790 NJ Census are Moses Colyer, Piscataway, Middlesex; John Colyer/Colyor, Bernards Twp., Somerset, Thomas Colyer, also in Bernards Twp.; and possibly an Isaac "Coll," of "W. Precinct," Somerset. Up to about 1787 there were also a James and John Collier in Woodbridge, Middlesex County.
I have been able to trace a few of these lines down to the present day, but am at a dead end on the descendants of a Lt. Thomas Collyer who served in the Revolution from Somerset County. This is possibly the individual in the 1790 Census, above.
If we can make a connection, I have much more early information.
