Are there materials of interest to genealogists?

Yes, our latest volumes provide brief identifications, including birth and death dates, of the individuals who corresponded with Jefferson. Our volume indexes are a good place to explore whether your ancestor appears in Jefferson correspondence. Sometimes the fact that someone wrote to a famous person helps prevent an otherwise obscure individual from being lost in the pages of history.  We also frequently turn to published genealogical histories to help us fill in the blanks on some of the subjects we identify.
