I would have used
Lucy Beatrice Maria - the mns are honouring. I find
Emiliana too heavy and complicated, but
Lucy Emily won't work.
Lucy Amelia Rose?
Ida Emily Joan? Not sure why that one works for me, but it does.
Greta is OK as long as it doesn't turn into Greeta, as in 'greet her'.
Greta Madeleine Rose is fine.
Greta Josephine Ruth? I know an
Enid, married to a friend: very nice person. Her nn, going back to childhood, is Dinnie!
Enid Caroline May is good; I prefer that spelling.
Enid Caroline Rose?
