Jerry I am not aware of any county census however there are tax records for most years and for most towns in Dauphin County. These record list the heads of households divided into three catagories Freeholders, Tennants and Single Men. The LDS has the records on microfilm from 1785 to 1850. The State Archives has them till around 1895. If searching in Harrisburg city directories could be used. As far as vital records are concerned you will need to search church records. For a brief period between 1852 and 1855 some records were kept by the counties. However even these are incomplete. Ray Rhoads
