Celebrating 125 Years

Our mission is to provide leadership and support in promoting genealogy through education, preservation, and access to Pennsylvania-related genealogical information.

Founded in 1892 as a non-profit organization, the Genealogical Society of Pennsylvania (GSP) was among the first in the United States to recognize the value of collecting and preserving the vital and personal records of those ancestors whose lives now comprise our American History.

GSP is committed to preserving and publishing previously unpublished primary sources. The continuing dedication to this service enables the Society to make an increasingly significant contribution to the cultural life of our city, state, and country.
