Mavis is a name of Latin origin, derived from the Roman family name Maximus. It signifies 'greatest' or 'largest', suggesting strength and magnitude. This unique moniker has been traditionally more popular among English-speaking countries like the UK and Australia, though it's also occasionally used in other regions. Mavis is often associated with a warm and friendly personality, but as previously stated, this isn't a trait universally linked to bearers of this name. In literature and pop culture, the name Mavis has been used for characters in works such as Roald Dahl's "The BFG" and the animated series "Foster's Home for Imaginary Friends".
"The name Mavis was quite popular at the turn of the century, with peaks in popularity between 1916 and 1920, and again from 1923 to 1926. After a decline, it regained some traction in the late 1930s and even made a small resurgence in 1949 and 1964."
