I think that the descendants of Thomas were more to the east in New London and Middlesex counties in the early to mid 1700's.After the Revolution they started migrating to western Conn., Western Mass. and then a lot went to New York and points beyond. There are two Carrier genealogies I've seen but I'm not sure if either are in formal print or distribution. One is by a Helynn Carrier who currently lives in California and one I've used a bit by a Mr. George May. These may be available from the LDS libraries.
