There goes my weakness for girl V names, again, and I know it's similar to Vivian/Vivien which I just posted about. This name is not in this site's database, and I only know of its existence because of the actress Viveca Lindfors, who was Swedish, so I imagine it's a Swedish name. I like it, though given a choice I'd choose Vivien.
Do you like Viveca? Which is better, Viveca or Vivien?
