1970s and 1980s were peak decades for these names.
l'm a
Sanja and that was in top 5 for my generation.
Dunja wasn't anywhere near that. We don't have popularity stats for these years, only top 10 for decades and it isn't on there.
As l said l've only met 3-4 Dunjas in my life, on the other hand I was one of 4 Sanjas in my classroom of 30 in school. Just to give you an idea.
Yeah, they’re dated now. I guess something like
Heather, everyone knows one, but no kids with these names.
