We've narrowed down the options to Phoebe or Helena. Her older brothers are Hector and Jasper. Our surname starts with F. So slight concern about an alliterative sound with Phoebe (although it runs together nicely). And Helena would share a first initial with Hector, but I'm not sure that matters too much.
Would be great to get some views on the following combinations of first name / middle name. Middle names all chosen because of significant meaning or association with an individual.
Phoebe Marianne
Phoebe Helena
Phoebe Maia
Phoebe Beatrix
Helena Marianne
Helena Phoebe
Helena Beatrix
Helena Florence
Thanks!
