Susannah or Sanna?

Which name would you choose and why?
I love the tradition of [name_f]Susannah[/name_f] and the modern friendly feel of [name_f]Sanna[/name_f]!

[name_f]Susannah[/name_f] wins for me-- I like traditional and I love the nn [name_f]Susie[/name_f]!

[name_f]Susanna[/name_f] with [name_f]Sanna[/name_f] as a nickname.

Really hard choice!
I adore [name_f]Sanna[/name_f] (plus you could nickname her “[name_u]Sunny[/name_u]” which is adorable) but [name_f]Susannah[/name_f] has more nickname options (in case she ends up disliking [name_f]Sanna[/name_f])
Still, I think you should go for [name_f]Sanna[/name_f]. It’s sweet, unexpected and unique

My choice would absolutely be [name_f]Susannah[/name_f] with the nickname [name_f]Sanna[/name_f].

Edited for privacy.

I find [name_f]Sanna[/name_f] more interesting but I like both. I like the idea of using [name_f]Sanna[/name_f] as a nickname for [name_f]Susannah[/name_f].

[name_f]Susannah[/name_f] is beautiful!

Since you love both, I would go with [name_f]Susannah[/name_f] nn [name_f]Sanna[/name_f] so you can call her both!
