Dear Ms. Comfort,
Thank you for posting your question on History Hub.
The National Archives is the repository for the permanently valuable non-current records of the Federal Government. Although only 1-3% of the records created by the Federal Government are transferred to the National Archives, our holdings consist of hundreds of thousands of records, many of which may be of genealogical value. The vast majority of our records are not name-searchable. You will need to begin your research by determining the agency with which your subject interacted and exactly what types of records you wish to see.
For more information on conducting genealogical research within our records, please visit our webpage: https://www.archives.gov/research/genealogy. You may also wish to consult the Family Search webpage, Getting Started with Family History and the Ancestry.com Genealogy website.
We hope this information is helpful in beginning your search.
