(The name "Pennyworth" was first used for Alfred in 1969 and thereafter it has been assumed that his father was named Jarvis Pennyworth; as it is customary for British domestic servants to be called by surname it might have been implied on Alfred's introduction that Jarvis was the surname he shared with his father; the surname "Beagle" was explicitly used for Alfred starting in 1945 and on the introduction of "Pennyworth" this is treated as having always been their name by retcon).
