1. Both are lovely but I love
Adeline best.
2. Yes, they are both lovely. Are
Charlotte and
Maria family names? Otherwise
Evelyn Marie might flow a little better.
3. It depends. If you use nn, they are not too similar (
Ada,
Addie,
Eva,
Evie).
4. Just do what you prefer. If you have many names you love, why not use two mn? Where I live (Sweden), it seems that two mn is the norm.
5. I love Anabel (prefer it spelt
Annabel).
"You sought a flower and found a fruit. You sought a spring and found a sea. You sought a woman and found a soul. You are disappointed."
"It does not become me to make myself smaller than I am." (
Edith Södergran 1891-1923)
