Baby Girl Names that Start with the Letter O
From Obelia to Ozora and everything in between, hundreds of baby girl names starting with the letter O along with the meanings and origin of each name.
Baby Naming Tip – Consider how long your child’s first name will be and the number of syllables it has. Very long first names when paired with long last names can be difficult to write and fit in forms, and very short ones may sound or look odd when written out. Baby girl names flow best when the number of syllables is different in the first name and last name.
