Galindians

Johannes Voigt (supported by many others) suggested that name is derived from the Baltic word *galas ("the end", probably synonymous to "located farthest", "located near the border of the territory or area"), alluding to the fact that they settled for some time further west and further east than any other Baltic tribe.

[6] Second, the Hypatian Codex mentions that Sviatoslav Olgovich defeated the Golyad' who lived up the Porotva (now Protva) river in 1147 ("взя люди Голядь, верхъ Поротве").

[1] In addition the Novgorod Fourth Chronicle mentioned that Mikhail Khorobrit "was killed by 'Litva' (Lithuanians) on the Porotva" (Russian: убьенъ бысть от Литвы на Поротве, romanized: ubien byst' ot Litvy na Porotve) in 1248.

Historian Valentin Sedov [ru] argues that this 'Litva' people were descendants the Galindians, because he sees no reason why would actual Lithuanians make military excursions so far from their lands.

[5] In folk traditions that lived on into the 20th century there are tales about mighty giants with the (personal) name Golyada.
