In this guide, you will find a series of research articles packed with helpful ideas for tracing ancestors in big cities like Philadelphia and Pittsburgh, as well as 67 counties throughout the state. Pennsylvania Online Genealogy Records will help you quickly discover what is available online. In Pennsylvania, birth, marriage, and death records generally do not begin until the late 1800s and early 1900s. Church records are a valuable substitute for birth, marriage, and death records if you are searching in an earlier time period. In the county guides, such as Berks County, a great deal of effort has been made to determine which church records are available online at sites such as Ancestry, FamilySearch, and USGenWeb.
