American historians have tended to dismiss Madison Hemings's memoirs for both broader and more specific reasons, citing examples of individual historians who doubted the credibility of a slave's account. James Callender made accusations about the Jefferson-Hemings affair for political reasons during a time of major disagreements and in-fighting between opposing parties. Callender got his information about the affair from Jefferson's nephews. Circumstantial evidence like residency and travel patterns suggest Jefferson was probably the father of Hemings's children while ruling out other men, based on Gordon-Reed's analysis. Oral histories from one side have traditionally been deemed more reliable than the other side.
