Reginald is an English name of Germanic origin, derived from 'Hrēthel' and 'Weald', which mean 'powerful' and 'to rule'. It was brought to England by the Normans after the Norman Conquest in 1066. Reginald is a name that has been used for centuries, with notable bearers including King Reginald I of Burgundy (921-937) and Reginald II, Duke of Bavaria (976-995). It fell out of fashion during the Middle Ages but experienced a revival in popularity during the Victorian era. Today, Reginald is still considered a classic, traditional name.
The name Regionald appears to have been popular among parents during the mid-20th century, with a spike in usage between 1957 and 1960. However, it seems to have fallen out of favor thereafter, as there was only one birth recorded for this name after 1968, which occurred in 1980.
