Sibling set names

Hello! Im curently pregnant with my 4th and final baby, a girl! and need help with baby names. My other children are, Flora Ottilie, Arthur Rowan & Olive Romilly

I’m from England but we are currently living in Midwest USA.

Names we like - Cecily, Clementine, Florence. Her middle name may be Willa as it’s a family name (undecide)

Lots of suggestions please!!! thank you
