Of the three- which do you prefer: [name_m]Griffin[/name_m] “[name_u]Finn[/name_u]”, [name_u]James[/name_u] “[name_u]Jamie[/name_u]” or [name_m]Jasper[/name_m] “[name_m]Jack[/name_m]”?
Out of [name_m]Griffin[/name_m], [name_u]James[/name_u], and [name_m]Jasper[/name_m] I prefer [name_m]Jasper[/name_m]. As stand alone names I adore [name_u]Finn[/name_u] (and [name_u]Finley[/name_u]) and [name_m]Jack[/name_m].
I like all three names in part, but as a first name I would definitely choose [name_m]Jasper[/name_m] nn: [name_m]Jack[/name_m].
As a long name, I prefer [name_u]James[/name_u], but I prefer the nickname [name_m]Jack[/name_m].
[name_m]Griffin[/name_m] with nick name [name_u]Finn[/name_u] would be my choice.
[name_m]Griffin[/name_m]!
[name_m]Griffin[/name_m] [name_u]James[/name_u] is a great name!
I also love the name [name_m]Jasper[/name_m] but do not like [name_m]Jack[/name_m] as the NN.
I vote for [name_u]James[/name_u] with the nn [name_u]Jamie[/name_u]. I love [name_u]Finn[/name_u] and [name_m]Jack[/name_m], but I’m not a huge fan of [name_m]Griffin[/name_m] or [name_m]Jasper[/name_m].
Definitely [name_m]Griffin[/name_m] “[name_u]Finn[/name_u]”. It’s so handsome!
[name_m]Griffin[/name_m] as the full name, [name_m]Jack[/name_m] as the nn.
I love every name you mentioned, but honestly, I strongly prefer [name_u]Finn[/name_u] as a full name.
I love all 3 full names. [name_m]Griffin[/name_m] “[name_u]Finn[/name_u]” is on my own list.
I love [name_u]James[/name_u], but I’ve known 3 girls called [name_u]Jamie[/name_u] with this spelling (and one boy ‘[name_u]Jamey[/name_u]’), so it looks feminine to me. It also feels a wee bit dated, not in a bad way, but it’s in the same category as [name_u]Casey[/name_u] for me. If that makes sense…
I also love [name_m]Jasper[/name_m] AND [name_m]Jack[/name_m]… don’t necessarily get [name_m]Jasper[/name_m] nn [name_m]Jack[/name_m]. Still cute though.
it’s between [name_m]Griffin[/name_m]/[name_u]Finn[/name_u] and [name_m]Jasper[/name_m]/[name_m]Jack[/name_m] for me. Good luck!
I like [name_u]James[/name_u] the best. I probably wouldn’t use [name_u]Jamie[/name_u] as a nn, I’d probably us [name_u]Jem[/name_u], [name_u]Jemmy[/name_u], or [name_u]Jay[/name_u]. I like the name [name_u]Finn[/name_u], but am lukewarm on [name_m]Griffin[/name_m]. I love [name_m]Jasper[/name_m], but probably wouldn’t use a nn ([name_m]Jack[/name_m] is a bit of a stretch for me, but I like the nn [name_m]Jack[/name_m]).
[name_m]Griffin[/name_m] “[name_u]Finn[/name_u]” would be my pick.
I like [name_u]Finn[/name_u] quite a lot (although I prefer [name_u]Flynn[/name_u] or [name_m]Finnian[/name_m]), but I’m not a fan of [name_m]Griffin[/name_m] at all (I wish I could see what all the fuss is about!), and while I think [name_u]James[/name_u] is classic and handsome, it’s always seemed a tad boring. I [name_u]LOVE[/name_u] [name_u]Jamie[/name_u] on a guy, but I’m not such a huge fan of [name_u]James[/name_u]. I like [name_u]Jameson[/name_u] more. Which leaves me with [name_m]Jasper[/name_m]. I find it really hard to picture a little boy (or even anyone) with the name [name_m]Jasper[/name_m], but I like it much more than [name_u]James[/name_u] or [name_m]Griffin[/name_m], and I adore the nn [name_m]Jack[/name_m] (which, I find to be a pretty huge stretch for [name_m]Jasper[/name_m], but I still love [name_m]Jack[/name_m] best anyway, so [name_m]Jasper[/name_m] gets my vote. 
Good luck!
