Dion is of Greek origin, meaning 'devoted to Dionysus', the god of wine and festivity. It is derived from the Latin form Dionysius, which was used by several early saints. The name gained popularity in England during the Middle Ages due to the influence of French culture. It has since been used steadily but not excessively throughout history.
The name Dion experienced significant fluctuations in popularity over the decades. It started with low numbers in the 1930s and 1940s, but began to gain traction from the late 1950s onwards, peaking at 53 births in 1970. The 1980s saw a steady decline, with fewer than 20 births per year after 1980. Since then, Dion has maintained a modest presence, with annual birth numbers ranging from 6 to 22 between 1985 and 2022, excluding years where data is missing or not available. In total, there have been 1233 births named Dion over this period.
