Ruthenian (Rusyn) Names

This chic Ukrainian form of Helen is relatively unknown outside of its native country, but it definitely has international appeal. Olia or Olenka are the usual Ukrainian diminutives, but tomboyish Oli or Leni could work too.

This Slavic form of the Norse name Helga is a classic in many Slavic countries, including Russia and Poland, where it currently ranks within the Top 100 girl names. It has historically ranked among the most popular names in countries including Ukraine, Latvia, Spain, France, Serbia, Greece, the US, and many more. Olga is a common name even in Scandinavian countries, such as Sweden and Norway, despite Helga being a more traditional choice. Olha is the uniquely Ukrainian variation.

Petronella, and its shorter sister Petra, are both feminizations of Peter. While Petronella is a name with deep history, it's extremely rare. It was given to no baby girls on record in the US last year.
