Jeffory, of Germanic origin, means 'peaceful'. It is a variant of Jeffrey, which has been popular throughout the centuries, particularly in the United Kingdom and the United States.
"Jeffory peaked in popularity during the late 1950s and early 1960s, with a high of 51 births in 1962. However, it has since become quite rare, with fewer than 10 Jeffory births occurring each year after 1987."
