Examples
I thought of a redhead who lived in a farm like Green Gables type, and after working in the farm she would go to sing to the river or walk near the meadows, and is an eternal optimist and always finds the good things of life, even if she does not have much. She has three lizards and a cat. She is smart and adventurous and never gives up. That is how I picture a Clémentine :)) Clémentine is such a name full of live and countryside spirit!
I picture an Héloïse as a painting of the French impressionist era. In the park, in the green, a young woman wearing a light blue hat and a light spring dress of the 19th century. She is an artist, and paints as well; her personality is somehow like Amy March. Héloïse is well educated and mature, yet enjoys interactions with others. She is blond and has eyes colour of the sapphire. Héloïse is a gem of the Medieval Times and romance poems (Abelard et Héloïse) yet so bubbly today!
I imagine a Klara like this - she always wears long dresses of past centuries, of dark colours, and always wears a ribbon colour of her dress. She is very pale. She does not speak almost at all at people, and loves to stay at home playing piano. She is a musicist. When she goes out though she is always inspiring people with the music. The house is old and Gothic vibe. Aesthetics - German Dark Academia - 17-18th century. Klara is a name with old fashioned style in it yet unexpected!
Irina laughs a lot, is always happy, cheerful, youthful, with long black hair and dark eyes, but skin of colour of a swan. She sings, she dances, she is extrovert. There is life in Irina. The sound of the name is also very melodious and sweet.
Elsa is the oldest sister, she is a glamorous black and white movie star, like Greta Garbo or Marlene Dietrich vibe. She is intellectual also and full of spirit, and with some mystery. Elsa is a name with personality and strength!
