Maciej Stryjkowski relates the origins of this family to Alšis Ramuntavičius (Polish: Holsza Romuntowicz) (c. 1250), coming from the line of Dausprungas.[2] According to the ancient genealogy of Lithuanian princes written by Teodor Narbutt, Alšis was to be the eleventh generation of the Palemonids, and was to give rise to the Alšėniškiai, who ended in the late 16th century.[2] What Stryjkowski or Narbutt wrote is very dubious as the distance of time is too large to prove it documentally.[2] The history of this house, already based on some writings, only begins with Jonas Alšėniškis (c. 1379-1402), whose father Algimantas (Ougemundes) presents the first historically proven generation of the Alšėniškiai.[2]
For the first time Alšėniškiai family is mentioned in written sources at the end of the 14th century when Ivan, son of Algimantas, assisted Vytautas in the Lithuanian Civil War (1381–1384) against Jogaila. Such a late mention of strong family is attributed to the geographic location of their domain: Alšėnai was neither in the way of the Teutonic or Livonian Orders.[3] In contemporary sources, Algimantas is mentioned only in Ivan's patronymic name. However, late and unreliable Lithuanian Chronicles created a fanciful genealogy of Algimantas that connected him to the legendary Palemonids that allegedly hailed from the Roman Empire. Modern historians have discarded the genealogy as a work of fiction not based on historical facts.[3]
