Middle Ramu languages
The Middle Ramu or Annaberg languages are a small language family of Madang Province, Papua New Guinea. It is no longer accepted as a valid grouping by Glottolog, but is accepted by Foley (2018). Wurm (1982) classified Aian, at his 'family' level, in a more distant stock-level relationship with Rao (Annaberg):
Annaberg
Rao (Annaberg)
Aian family: Anor, Aiome

The Annaberg family is generally classified among the Ramu languages of northern Papua New Guinea. References
