I want to give my daughter an English name: Swan, or Little Swan. I don't know if I can. If possible, which word is appropriate?

Swan is English, the heroine in Pirates of the Caribbean is called elizabeth swann, and the last one is surname, which is a variant of the word swan. Hansika means Little Swan, Odette is the name of the white swan in Swan Lake, Swanhilda is a German/Swedish name and a variant of the word swan, so the landlord can choose it at will, but I personally think the last name is more emotional.
