or others (I’m sure there’re a lot more)?
I’m considering the name, but I’m not sure which spelling/pronunciation is better? What do you think in general? Does it sound old-fashioned?
The last one, [name]Polina[/name], is by far my favorite, because it’s Russian form of the name and I have Russian heritage. It also looks quite unique to me.
Also, what are some possible nicknames and middle names?
Please tell me what you think!
I really prefer the first two! [name]Pauline[/name] or [name]Paulina[/name]. I think in terms of nicknames you could use [name]Polly[/name], [name]Lina[/name], [name]Linette[/name], or [name]Linny[/name].
I like [name]Polina[/name] because it could easily lead to [name]Polly[/name] as a nickname. But honestly, all of them are good choices.
[name]Polina[/name] is best 
Pretty names! If you’re in the U.S.: Personally, I’d use the standard [name]Pauline[/name] or [name]Paulina[/name] to avoid spelling and pronunciation problems. Whereas, [name]Pauline[/name] and [name]Paulina[/name] have the “aw” vowel sound, [name]Polina[/name] is likely to be pronounced with a long O… “Poh-lee-nuh.” However, if that is the pronunciation you prefer, then that would work, but she may need to spell the name out for everyone.
This makes the most sense to me. [name]Even[/name] though I know [name]Polina[/name] is a variation of [name]Paulina[/name], I’m still inclined to say “Poh-lee-nuh.”
Since [name]Paul[/name] is so very masculine I prefer the most feminine looking/sounding of them best… [name]Paulina[/name]
I am firmly in the [name]Polina[/name] camp! [name]Love[/name] that is is a little bit different has the heritage and it looks pretty to my eye
I like [name]Polina[/name] the best but by far prefer just using the nn [name]Polly[/name].
I love [name]Polina[/name]. It’s exotic and seems to have the most meaning to you.
