Salut Camille!
1. What is the meaning of the name "Tzivia"? I believe it's a male name (though it could be female...) and it has roots in Hebrew/ Yiddish.
--- The name Tzivia looks like a form of Tzevi which comes from the Hebrew name Zwi meaning "stag".
2. What is the meaning of "Gessina", which is female and Scandinavian?
--- There's no woman in Sweden, Norway or Denmark with that name at all. Maybe you mean Gesina (I found at least 8 women in Sweden and 4 in Denmark with that name). Gesina is a form of Gesa. Both are Low
German pet forms for Old Norse and Old
German names beginning with Ger- (like
Gertrud, Gerhild, Gerlind...). The meaning of "ger" is "spear".
3. How do you pronounce the names...
...
Gittel? --- GUI-tell (GUI like in "guitar" but with a short i like in "with". Stress on the first syllable)
...
Crina? --- CREE-nah (just a guess, I don't know!)
...
Siobhan? --- shee-VAWN (stress on the second syllable)
Regards,
