Many of the first names of the listed characters are not typically Finnish at all. Most them suggest a person being of either Swedish or Russian descent. Only Paavo is a true Finnish first name, while Per, Jan, Birger, Gustaf, Knut and Jan are more common first names in Sweden. Viktor is clearly Russian.
Number of names used for Finnish characters (Engel, Vallgren, Simberg and Tyko Gallen) have been inspired by Finnish artists.
