Sweden are definitely going through a retro phase. 10 yrs ago when my nephews were born, it was very much early 20th century:
Oskar, Lukas, Markus, Johannes, Jonatan, David, Alfred, Albert, Karl for the boys
Hannah, Sarah, Viktoria, Johanna, Ida, Emily, Lovisa, Beata for the girls
Now they seem to be moving into the mid-20th century: Edvin, Edvard, Doris, Ingrid. Basically, you see the same names on the birth announcements/christenings and the obituaries.
I can't wait to see the Fifties: Clarke, Elvis and the rest.
