Agree, my first thought here is Re-SHAR-da, but then next step I had to think of a former neighbour of mine, she's
Riccarda or Rikkarda (like
Rebecca or
Rebekka, don't know exactly)-
so it's Re-CARD-a and I must say, I like it;
way fresher than
Rebecca and not so over-used.
Whereas others than
Alfreda, Manfreda or Norberta etc. aren't my cup of tea.
