I like [name]Sophie[/name] [name]Kate[/name] a lot! [name]Addison[/name] [name]Kate[/name] is nice too, I personally wouldn’t have made that connection and I don’t think it’s that big of a deal. While I am all for family names, especially in the middle, I just don’t think [name]Beckham[/name] sounds great for a girl. [name]Just[/name] my opinion though. I just think [name]Sophie[/name] [name]Kate[/name] or [name]Addison[/name] [name]Kate[/name] are much better choices! Good luck!
I love [name]Sophie[/name] [name]Beckham[/name] [name]Shepard[/name] - esp with it’s family connections. This would be my obvious choice.
[name]Addison[/name] [name]Kate[/name] [name]Shepard[/name] just makes me laugh. I don’t think it would be a good idea to use that. Why?
On the show, [name]Grey[/name]'s Anatomy, there’s a famous (now gone, but still famous) character named [name]Addison[/name] [name]Shepherd[/name]. The actress that played [name]Addison[/name] is [name]Kate[/name] [name]Walsh[/name].
So [name]Addison[/name] [name]Kate[/name] [name]Shepard[/name] makes me assume you’re a superfan of [name]Grey[/name]'s. Lol.
[name]Sophie[/name] [name]Kate[/name] is my favorite from your list.
[name]EDIT[/name]: I posted this before I read through everyone else’s posts pointing out the same thing. Lol.
I like [name]Sophie[/name] [name]Kate[/name] best.
[name]Addison[/name], [name]Sophie[/name] and [name]Kate[/name] are extremely popular. [name]Beckham[/name] is the standout-- the name that keeps things interesting, that will make people remember your birth announcement. I quite like [name]Sophie[/name] [name]Beckham[/name]-- the other combos to me seem to fade into the onomastic background.
That being said-- are those definitely the final four names on your list? Because while I like [name]Sophie[/name] [name]Beckham[/name], ‘[name]Sophie[/name]’ being a variant of the #1 name in [name]America[/name] right now would give me a bit of pause. Would you be interested in something sweet and [name]Sophie[/name]-like, such as [name]Sylvie[/name]? [name]Sylvie[/name] [name]Beckham[/name] is ravishing.
I love [name]Kate[/name] as a middle name, it’s mine and I love it 
I really like the name [name]Sophia[/name] [name]Kate[/name] as well as [name]Sophie[/name] [name]Kate[/name].
Good [name]Luck[/name].
I like [name]Sophie[/name] [name]Beckham[/name] the best! It’s unexpected, interesting, and has family significance
I like the flow of [name]Addison[/name] [name]Kate[/name] bests, but I like [name]Sophie[/name] better than [name]Addison[/name]. [name]Hope[/name] that helps!
Now that I know [name]Beckham[/name] is a family name, my vote goes 100% to [name]Sophie[/name] [name]Beckham[/name].
[name]Sophie[/name] [name]Beckham[/name] is great! Because [name]Beckham[/name] has familial significance, it gets my vote, no question.
