Hello, and thank you for posting your question on History Hub!
We suggest you refer to this related, previously answered question for guidance. Cara Jensen’s reply gives suggestions in obtaining personnel records and information about projects they may have worked on. This is especially useful since relevant records may be found in several repositories at the State and Federal levels.
Additionally, a search in the National Archives Catalog shows eleven records series concerning the Works Progress Administration (Record Group 69) and Pennsylvania. For access to these series, please contact the National Archives at College Park - Textual Reference (RDT2) via email at firstname.lastname@example.org.
Due to the COVID-19 pandemic and pursuant to guidance received from the Office of Management and Budget (OMB), NARA has adjusted its normal operations to balance the need of completing its mission-critical work while also adhering to the recommended social distancing for the safety of NARA staff. As a result of this re-prioritization of activities, you may experience a delay in receiving an initial acknowledgement as well as a substantive response to your reference request from RDT2 and RL-SL, where you may find their personnel records. We apologize for this inconvenience and appreciate your understanding and patience.
We hope this is helpful. Thank you again for submitting your question to History Hub!

We suggest reviewing the NARA web pages about non population census records that includes a listing by state for the 1820 through 1930 census. Also, please refer to the U.S. Census Bureau website about Business and Economy.
For information about the U.S. Census, see the Census Bureau technical documentation and questionnaires as well as NARA’s page on Census Records.
We hope this is helpful. Best of luck with your family research!
