If you are giving your daughter a middle name, the initials would be V.E.D. if it were
Verity Elizabeth Davis or whatever middle name you choose. It isn't as if you are using S.T.D. initials.
Beatrix and
Flora are both lovely.
Beatrix is traditional and steadfast but with a bit of fairytale glamor.
Flora is refreshing and nature inspired.
Bea is a bit incomplete.
Twyla is eccentric and zany.
Sybil strikes me as tremulous like a timid rabbit or a senior citizen with a quivering voice.
