Mai Brat languages
The May Brat languages are a small language family of the Maybrat Regency, Bird's Head Peninsula of New Guinea. They are not closely related to any other language, and though Ross (2005) assigned them to the West Papuan languages, based on similarities in pronouns, Ethnologue (2009) removed them as an independent language family.
