A Maryland man who in the 1980s was convicted of espionage and later pardoned for leaking spy satellite photos to a British magazine has been charged with stealing government records related to a famous Naval historian who was his grandfather.

Samuel Loring Morison, of Crofton, was arrested Tuesday but released pending trial. Prosecutors allege Morison, 69, stole government records tied to his grandfather, Rear Adm. Samuel Eliot Morison, from a Navy archive in Washington.
