  The name Askold
  Askold
  Also — Oskold, Oskol'd, Oskolod. (Осколд, Оскольд, Осколод)
  There are several versions of the origin of the name Askold. The most likely version interprets it as the Norse name Haskuldr or Höskuldr. However, the spelling Askold may only be a change in the Scandinavian manner (similar to Vytautas – Vitold)." According to Doctor of Historical Sciences, professor Igor Danilevsky, who is a specialist on the history of Kievan Rus, the Scandinavian origin of the name is certain and it has long been proved.
  The suffix -ald- is found in Celtic names. There is also a theory of the Hungarian origin of the name, which has no sufficient grounds.
