Seeking information about Daniel Swiderski's brother

Is this the person you are looking for?  According to census records he worked in the coal industry at least through 1920, but lived on a farm in Westmoreland Co PA (about 20 miles south of Slickville).  In 1930 he is listed as a farmer.  He and his wife had many children, one named Mary, but none named Pauline.

Dear Mr. Swiderski,

Thank you for posting your request on History Hub!

We searched the National Archives Catalog and located the Population Schedules for the 1910 Census, the Population Schedules for the 1920 Census, the Population Schedules for the 1930 Census, and the Population Schedules for the 1940 Census in the Records of the Bureau of the Census (Record Group 29) that may contain information about your grandfather’s brother.   The 1940 Census  schedules are digitized and available using the Catalog. See NARA’s 1940 Census Records web page for more information. For access to the non-digitized schedules, please contact the National Archives at Washington, DC - Textual Reference (RDT1) via email at archives1reference@nara.gov. 

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 RDT1. We apologize for this inconvenience and appreciate your understanding and patience.

You may wish to search Ancestry.com or FamilySearch.org for the U.S. Census. There may be a fee for using Ancestry. Instead, check for access at your local library as many library systems subscribe to these sites, making them free for their patrons.

We also suggest that you search the Pennsylvania State Archives, Pennsylvania Births and Christenings, 1709-1950 FamilySearch index and review the FamilySearch Research wiki for Pennsylvania Genealogy.

We hope this is helpful. Best of luck with your family research!
