Dear Mr. Polhemus,
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 Population Schedules for the 1940 Census, and the Population Schedules for the 1950 Census in the Records of the Bureau of the Census (Record Group 29) that may contain information about Carolyn / Caroline Polhemus living with her husband Clyde and daughter in New York (1940 census). We were unable to locate her on any additional censuses. The 1940 Census schedules are digitized and available using the Catalog. The 1950 Census also is available online. For more information about the non-digitized schedules, please contact the National Archives at Washington, DC - Textual Reference (RDT1) via email at firstname.lastname@example.org.
You may experience a delay in receiving an initial acknowledgment as well as a substantive response to your reference request from RDT1. We apologize for this inconvenience and appreciate your understanding and patience as we balance mission-critical work and the safety of our staff during the pandemic. Please check NARA’s web page about COVID-19 updates for the latest information.
You may wish to search Ancestry or FamilySearch for the U.S. Census. There may be a fee for using Ancestry. Instead, please check for access at your local library as many library systems subscribe to these sites, making them free for their patrons.
We suggest that you review NARA’s Resources for Genealogists, as well as the History Hub Blog titled Suggestions and Advice for Family History Researchers. Also, the FamilySearch Research wiki for United States Genealogy may be useful.
We suggest that you contact the Pennsylvania Department of Health to request a search for the birth certificate of Carolyn or Caroline Greber who was born in that state about 1912. The birth certificate will include the parents of her parents. Although we were unable to locate a death record for her, you should request a search for her possible death certificate from the New York State Department of Health.
You may wish to note any name variants (first & last names) to broaden your search for the surrounding years. In addition, the FamilySearch Research wiki for Pennsylvania Vital Records and New York Vital Records may be helpful.
We hope this is helpful. Best of luck with your family research!
