The census I found was the 1863 Septennial Census. It will be online soon. The so-called Pennsylvania Septennial Census, was taken from 1779 to 1863 and bears the name of census but looks more like a tax list. These records - relatively few of which have survived - were generated to enumerate taxpayers for the purpose of determining representation in the state legislature. The septennial census returns usually list only the names and occupations of taxables. This would be the first and last Septennial Census for Cameron County.
