Where Can I Find Drake Ancestry From 1800-1900 In PA?

I am a member of Ancestry.com and it has many wonderful sources to trace specific people in specific locations, such as Immigration records, Census records, Voter registration, etc.  If you do not wish to join an ancestry organization, the next best way is to write to the vital records office of the area you are interested in with a description of the people you need information about and they are usually helpful, sometimes for a fee.  If you live close by, most areas have a historical society than can also be of assistance.  Good luck.
