Golyad and West Galindian have been proposed by scientists to have had a common origin that is based on two ancient authors using the common name of Galindian for both of them. In order to prove this hypothesis, they investigate common features between
Prussian/West Galindian and Golyad.
Marija Gimbutas suggested that both the Golyads and West Galindians name could both originate from the word for end or borderland in Lithuanian () and Latvian (). This name could have come from the Golyad being the furthest Baltic tribe in the east. Some theories that propose a relationship between West Galindian and Golyad are that the West Galindians migrated from their homeland in
Prussia towards the Protva basin. In this theory, another group who also migrated West during this period, the
Goths, are believed to have also inspired the language and culture of the Golyads. Another theory is that the Golyads were West Galindians that were
captured during wars with the
Grand Duchy of Lithuania and the
Russian duchies, but this is unlikely as local Slavs wouldn't have replaced their own names for regions with names from their POWs. == West Galindian==
