On the 1798 Chesterfield/Willsborough Tax list I find the ancestor I am looking for....then he is in Lewis in 1806 on a list of people working on roads.... but he may not have moved at all? Was this geographical area the same? I am thinking that when the new towns were formed that he resided in a different tax area but was still in the same place.... Any idea about that? I think it was all within Essex County but then the boundary lines of the county changed also. Thanks J
