[name]Seraphina[/name] or Serphine- [name]Love[/name] that it’s Hebrew and maybe [name]Fifi[/name] as a nickname

[name]Susannah[/name]- honor my mom and like [name]Sue[/name] as a nn
[name]Bethany[/name]
Other suggestions welcomed
[name]Seraphina[/name] or Serphine- [name]Lovely[/name]… prefer [name]Seraphina[/name]… and I think [name]Fifi[/name] is a cute pet name… although I just cant see a [name]Fifi[/name] at school… probably mentally cant get of there stereotype behind [name]Fifi[/name]…
[name]Pearl[/name]- dont know if [name]Pearl[/name] is getting trendy, I dont live in the US, but have not met anyone with the name or mn of pearl (I am an american living on a military base overseas)
[name]Dorothy[/name]- [name]Dottie[/name] or [name]Dory[/name] – not loving it… but if I had to choose [name]Dottie[/name] is a much cuter nn in my oppinion.
[name]Susannah[/name]- honor my mom and like [name]Sue[/name] as a nn — [name]Susannah[/name] is beautiful… dont like [name]Sue[/name]… I would prefer Susa or anna as a nn.
[name]Bethany[/name] — I know a 20yr old [name]Bethany[/name], she is a wonderful young woman so I like this name… wouldnt use it my self, not my style and very bad connection to a [name]Beth[/name] but that’s just me.
[name]Seraphina[/name] / [name]Seraphine[/name] - Really like both, but prefer [name]Seraphine[/name] slightly.
[name]Pearl[/name] - It’s one of the few names in its category I’m actually not that fond of.
[name]Dorothy[/name] - I prefer the sound of [name]Dorothea[/name] to [name]Dorothy[/name], but it’s nice.
[name]Susannah[/name] - I love [name]Susannah[/name]. As a matter of fact I love [name]Suzanne[/name] and [name]Susan[/name] too. Not a fan of the nickname [name]Sue[/name], I like [name]Sanna[/name] better. 
[name]Bethany[/name] - Like it a lot.
[name]Seraphina[/name]- lovely. Prefer this over Serephine. I dont’ care for [name]Fifi[/name], sounds like a dogs name.
[name]Pearl[/name] -again, very lovely. I don’t think it’s trendy, I’ve never met one (old or young).
[name]Dorothy[/name] -too [name]Wizard[/name] of [name]Oz[/name] for me.
[name]Susannah[/name] -I like this, feels sort of warm and country-ish.
[name]Bethany[/name] -Hate this name. Absolutely hate it.
