Both Fairfield and Litchfield tcounties of Connecitcut had not been established yet. Aa a Connecticut resident, I seem to recall Fairlield County being established about 1666. Litchfield County didn't exist until 1751. Since there has not ever been another town or city of "Norwalk" except that in Faifield, perhaps you might wish to rethink the death and burial place-name strands.
For what it's worth ... or not,
