Missing New Hampshire Censuses
The 1800 census records for Rockingham County did not include the following towns: Atkinson, Greenland, Hampton, Hampton Falls, Londonderry, Northampton, Pelham, Plaistow, Salem, Seabrook, Stratham, Windham.
The 1800 census for Strafford County did not include the following towns: Alton, Barnstead, Brookfield, Effingham, Gilmanton, Middleton, New Durham, Ossipee, Tuftonboro, Wakefield, Wolfeborough.
Nine of those towns do have published Direct Tax records from 1798. Heritage Books published those records for each of the towns, which are: Alton, Brookfield, Effingham, Middleton, New Durham, Ossipee, Tuftonboro, Wakefield, Wolfeborough.
Those records are an excellent substitute for the missing census records from 1800 for those towns.
All 1820 census records for Grafton County are missing, as are the Rockingham County records from that year for the following towns: Gosport, Greenland, New Castle, Newington, Portsmouth, Rye.
Many Strafford County records are missing from that year as well. Only the Sanbornton, Gilford, Center Harbor, New Hampton, and Moultonborough records have survived.
