In the 1775-1778 Charles County Maryland Census (18 years and upward) the Port Tobacco Parish was listed as having a West Hundred and an East Hundred. My information is that Port Tobacco Parish (exact time period unknown) lay between Nanjemoy creek & Mattowoman creek on the west and north and the upper part of Wicomico River/Creek as it continues through the Zachia Swamp on the east side. Does anyone know the (approximate) boundary between the East and West Hundreds? Is my information about Port Tobacco Parish boundaries even close to being correct? Also, in censuses after 1790 is Trinity Parish just a later name for the combined King and Queen Parish and William and Mary Parish?
