Contact GSP

The Genealogical Society of Pennsylvania is located at 2207 Chestnut Street, Philadelphia, PA 19103


We welcome visitors but we ask that you make an appointment so that we can be prepared for your visit. 

On Thursdays, we have office hours from 11 AM to 3:00 PM, during which visitors can browse our library or meet with a genealogist for a 30-minute consultation. 

Call 215-545-0391 or email to schedule a visit.

We look forward to seeing you!


Our offices will be closed Friday, September 25 and Monday, September 28 due to the Pope's visit.


We enjoy hearing from genealogists worldwide! If you have general questions about the society, GSP's membership options, upcoming programs and events, please use the form below.
