The name Maeby is a girl's name of American origin. Maeby and discussed in our forums with posts like "Themed Families..".
From the experts:
Maeby sprang into the modern consciousness via the cult TV favorite Arrested Development, in which the appealing teen character Maeby's name is a nickname for Mae. It's also a homonym for Maybe, which undercuts its inherent cuteness. Is Maeby prime for a real life baby name? Sorry, but we can't resist: Maybe.
