History of Clarke County, Virginia Indexed edition

These five consolidated volumes constitute a surname index, with corresponding microfilm locations, to the residents of the Pennsylvania counties of Berks, Bucks, Lancaster, Luzerne/Wyoming, and Northampton respectively, in the year 1850. (Wyoming County was formed from Luzerne in 1842.) Although it was not possible, for reasons of economy, to list every person appearing in the census by given name, each book lists all the surnames appearing in the census for the county(ies) in question (i.e., Berks, 7,000; Bucks, 8,000; Lancaster, 15,000; Luzerne/Wyoming: 10,000; and Northampton, 5,000).
