I used to really like this name. the first thing that comes to mind when I hear it is free-spirited. But
Miranda Kerr slightly ruined it for me and it also reminds me of
Miranda Sings from YouTube. I've barely watched her but I find her style of humor super annoying.
Mira is a cute nickname.
I don't really like any of the combos cause I don't like the names so much but I'll comment on flow
Miranda Edith- don't like the flow of the ah and ee sounds between the names.
Miranda Josephine- this actually sounds really nice. Not a big
Josephine fan but
Miranda makes it prettier.
Miranda Antonia- the double a in the middle and double a ending is too muck for me.
Miranda Harriet-it's okay, feels off for some reason that I can't identify.
Miranda Isadora- same vowelly, souble a ending situation as above
Miranda Jillian- flows fine
Miranda Lavinia- Actually like
Lavinia, may be a bit over the top in this combo but it doesn't sound awful.
Miranda Ophelia- meh
Miranda Rosamund- this feels hard to say in my mouth for some reason.
Miranda Tamsin- not sure on the repeating "an", "am" sound.
I would personally pair it with something short, one or two syllables like
Miranda JuneMiranda JaneMiranda LucyMiranda Care
Miranda PhoebeMiranda LucilleMiranda Hazel
but something tells me those may be a little plain for your taste.
