We have officially decided against [name_u]Mika[/name_u], after a close friend used something similar for her dog.
So our other options are:
[name_m]Soren[/name_m] (mn [name_m]Arthur[/name_m] or [name_m]Hayes[/name_m])
[name_m]Magnus[/name_m] (mn [name_f]Arbor[/name_f] or [name_m]Arthur[/name_m])
[name_m]Enoch[/name_m] (mn [name_m]Hayes[/name_m] or [name_u]Valentine[/name_u])
Please tell us your favorite!
This is a tough one! I love all 3 of those names! The combos I like most are:
[name_m]Soren[/name_m] [name_m]Arthur[/name_m]
[name_m]Magnus[/name_m] [name_f]Arbor[/name_f]
[name_m]Enoch[/name_m] [name_m]Hayes[/name_m]
But ultimately my personal favorite is [name_m]Soren[/name_m]. I’ve always had a soft spot for that name. Really all of the are great.
My personaly favourite is [name_m]Soren[/name_m] [name_m]Arthur[/name_m], but I think [name_m]Magnus[/name_m] [name_f]Arbor[/name_f] would work wonderfully with your daughter’s name too. Not such a fan of [name_m]Enoch[/name_m] or [name_m]Hayes[/name_m].
[name_m]Soren[/name_m] [name_m]Arthur[/name_m] is by far my favorite.
[name_m]Soren[/name_m] [name_m]Arthur[/name_m]
I really love [name_m]Magnus[/name_m] [name_f]Arbor[/name_f] 
[name_m]Magnus[/name_m] [name_m]Arthur[/name_m]
[name_m]Magnus[/name_m] [name_f]Arbor[/name_f] is the most intriguing to me. I love [name_m]Soren[/name_m], but [name_m]Arthur[/name_m] and [name_m]Hayes[/name_m] make the combo a little dull. [name_m]Soren[/name_m] has a rather plain look to him, he could benefit from something more interesting in the middle. [name_m]Magnus[/name_m] is very common here, but I know he’s a lot less so in other parts of the world, and [name_f]Arbor[/name_f] is such a wonderful choice in the middle. I do think [name_m]Soren[/name_m] is a better stylistic match with Adeia, and my favourite name of all of these is [name_u]Valentine[/name_u], but my vote still goes to [name_m]Magnus[/name_m] [name_f]Arbor[/name_f].
[name_m]Enoch[/name_m] does little for me.
[name_m]Soren[/name_m] [name_m]Arthur[/name_m] is a great combo
[name_m]Soren[/name_m] by a mile.
I love both [name_m]Soren[/name_m] and [name_m]Magnus[/name_m]! For middle names, I always think meaning trumps flow.
I love [name_m]Soren[/name_m]! [name_m]Soren[/name_m] [name_m]Hayes[/name_m] is my favorite
[name_m]Soren[/name_m] [name_m]Arthur[/name_m]
[name_m]Magnus[/name_m] [name_m]Arthur[/name_m] or [name_m]Enoch[/name_m] [name_m]Hayes[/name_m]. I prefer [name_m]Enoch[/name_m].
I much prefer [name_m]Soren[/name_m].
I prefer either [name_m]Soren[/name_m] or [name_m]Magnus[/name_m]. Would take [name_m]Enoch[/name_m] off the list.
[name_m]Soren[/name_m] [name_m]Arthur[/name_m]
[name_m]Magnus[/name_m] [name_f]Arbor[/name_f]
I do love love [name_m]Soren[/name_m] [name_m]Arthur[/name_m], but Adeia [name_f]Marguerite[/name_f] ([name_f]Marguerite[/name_f], squee!) and [name_m]Magnus[/name_m] [name_m]Arthur[/name_m] is literally perfection. You can’t really go wrong with any of those options!
I was scrolling through the forums and I can’t believe I saw [name_m]Soren[/name_m]! I’m due in 3 weeks and that’s the name we have picked out for our little guy. [name_m]Soren[/name_m] [name_m]Patrick[/name_m], actually
Good name picking 
[name_m]Soren[/name_m] [name_m]Arthur[/name_m]. [name_m]Just[/name_m] lovely.
I love [name_m]Soren[/name_m] [name_m]Arthur[/name_m] and [name_m]Enoch[/name_m] [name_m]Hayes[/name_m].
