Welcome to GSP

The Genealogical Society of Pennsylvania Seal
The Genealogical Society of Pennsylvania (GSP) is a non-profit educational institution located at 2100 Byberry Road, Suite 111, Philadelphia, Pennsylvania 19116.  Founded in 1892, GSP is one of the oldest genealogical societies in the United States. Our mission is to provide leadership and support in promoting genealogy through education, preservation, and access to Pennsylvania-related genealogical information. GSP is committed to preserving and publishing primary source records and to helping people to search for their ancestors.

The Genealogical Society of Pennsylvania library will reopen to the public by appointment only starting June 14, 2021. Every visitor, volunteer and employee will be required to wear a mask. Social distancing will be implemented. Your safety is our priority! Our library hours will return to Monday, Tuesday, and Thursday from 10 am – 3 pm. If you would like to reserve a spot, please contact us at info@genpa.org or 267-686-2296.
