Sonja
Meaning
variant of Sonya, wisdom
The story
Sonja is the Scandinavian and German spelling of Sonya, itself a Russian pet form of Sophia, so beneath its northern sound lies the Greek word for wisdom. Norway crowned it: Sonja Haraldsen was an Oslo merchant's daughter whose romance with Crown Prince Harald ran nine patient years, the prince, the story goes, telling his father he would marry no one else; they wed in 1968, and she has been Queen Sonja of Norway since 1991, a devoted patron of the arts and a famously avid mountain hiker. Americans had met the name earlier through another Norwegian, the skater Sonja Henie, who won three Olympic golds and then glittered across Hollywood musicals on ice. In United States records Sonja has held a modest, steady place across the generations, more familiar than flashy, a quiet northern doorway into the wisdom names.
