Olgierd – Algirdas, King of Lithuania 1316 – 1344

There are three different versions of who are Giedymin's - Gediminas' father, grandfather and great-grandfather:

1. Polish-Lithuanian version: Pucuwerus Rex Lethowie, Trojden and Wołk.
2. Samogitian version: Butvydas - Pucuwerus, Dausprungas - Dowsprunk and Ringaudas - Ryngold.
3. Russian version: Витень - Witeń, Пройденъ - Projden and Видъ - Wid.

And these three versions are contradictory and irreconcilable, and this controversy will continue forever.
