Catherine Ilaria (Kay)
Honor Corinne (Nora)
Margaret Julee (Meg, Greta)
Philothea Jane (Thea)
Honor names: Arsenia, Ilaria, Philothea, Julee, Paula, Evelyn Mae, Pearl.
The outliers are Honor Corinne (I like how it sounds, I like possible nicknames of Nora and Cora) and Marian Elisabeth (I'm also fond of Mary, and Mary Rose as a double 1st).
The list would change drastically if I had to name ten girls all at once or ten girls one at a time without knowing if I would have another, like how normal life and pregnancies go, haha.
Ten all at one time would be:
Definitely hard to come up with ten middle names with meaning.
