We’re trying to find the perfect name for Hug0 Pr0sper!ty’s little sister. Her first name will be either [name_f]Rose[/name_f] or [name_f]Adele[/name_f], depending on which suits her better but we haven’t found a middle name that we find as enchanting as Pr0sper!ty.
We’re not quite sure exactly what we’re looking for but do know we want it to be meaningful. Doesn’t have to be a word name but we do like them. We’d also prefer something more uncommon.
Surname begins with S.
Evensong
Vespertine
Perpetua
Amaranth
Evermore
Agape
Viviana
Shiloh
Salomea
Elysian
Caelum
Seraphim
Meraki
Eunoia
Euphrasia
Euphemia
Serendipity
Hugo Pr0sper!ty is a wonderful combo!
