Dad’s pet name for Mark
The Roman emperor Marcus Aurelius Antoninus (161–180 CE) was a bit of a hero to Dad, and possibly the reason Mark was given such a then-rare name
Dad – 1950s
George Iliff – father of Mark, JM, G & Bel
Young Mark didn’t get the allusion at all, and was once heard to wail, “I’m NOT a relius!”
