Thanks to your advice we have narrowed it down to the following 2 names:
[name]Addison[/name] [name]Kate[/name] [name]Shepard[/name] ([name]Addison[/name] is a family name)
[name]Sophie[/name] [name]Beckham[/name] [name]Shepard[/name] ([name]Beckham[/name] is a family name)
We really like both and can’t decide. What is your favorite?
I’d go with [name]Sophie[/name] [name]Kate[/name] [name]Shepard[/name]. It sounds really pretty : )
[name]Beckham[/name] is FAR too well associated with the footballer to make it remotely usable. I appreciate that it’s a family name though. Maybe something with the ‘beck’ sound in it? [name]Sophie[/name] [name]Rebekah[/name]/[name]Rebecca[/name] sounds nice : )
[name]Addison[/name] will always be a boys name to me as it means ‘son of [name]Adam[/name]’.
[name]Sophie[/name] [name]Beckham[/name] would be my favorite! [name]Love[/name] the name [name]Sophie[/name] and [name]Sophie[/name] [name]Shepard[/name] sound really nice.
I like [name]Sophie[/name] more than [name]Addison[/name].
Personally, I like [name]Addison[/name] [name]Kate[/name] [name]Shepard[/name] the best, but I know most Berries will probably say [name]Sophie[/name] [name]Beckham[/name]. I just find [name]Addison[/name] [name]Kate[/name] to be very sweet, despite the unisex nature of [name]Addison[/name]. I don’t watch the show, but if [name]Addison[/name] [name]Shepherd[/name] is a character on [name]Grey[/name]'s Anatomy, that would give me pause for using it, though…
This is tough, I actually really like both of them.
[name]Addison[/name] [name]Kate[/name] has more of an elegant feel to me.
[name]Sophie[/name] [name]Beckham[/name] has a nice, fun sound.
[name]Both[/name] [name]Addison[/name] [name]Shepard[/name] and [name]Sophie[/name] [name]Shepard[/name] sound wonderful. Sorry I was zero help and good luck.
Honestly, the first thing I thought of was [name]Addison[/name] [name]Shepherd[/name] from [name]Grey[/name]'s Anatomy/Private Practice. I don’t much care for [name]Kate[/name] as a middle name, either, it’s become quite trendy.
My vote is for [name]Sophie[/name] [name]Beckham[/name]. Good luck!
I prefer [name]Sophie[/name] to [name]Addison[/name], but I agree that [name]Beckham[/name] is too closely associated with [name]David[/name] [name]Beckham[/name]. I too wanted to use [name]Beckham[/name]- this was before I knew who [name]David[/name] [name]Beckham[/name] was.
[name]Sophie[/name] [name]Beckham[/name] or [name]Sophie[/name] [name]Kate[/name] get my vote. I love the alliteration of [name]Sophie[/name] [name]Shepard[/name]!
Totally ditto this. Plus [name]Addison[/name] [name]Shepherd[/name] from [name]Grey[/name]'s/Private Practice is not the best association for a little girl. Not terrible, but certainly not the best. And the actress that plays her is [name]Kate[/name] [name]Walsh[/name], so [name]Addison[/name] [name]Kate[/name] [name]Shepard[/name] unfortunately would make me wonder if you were a huge fan of the series.
[name]Sophie[/name] [name]Beckham[/name] [name]Shepard[/name] is beautiful.
I Like both of them a lot but I lean more towards [name]Sophie[/name] [name]Beckham[/name]. I think its very beautiful and it honors family.
I would prefer [name]Sophie[/name] [name]Kate[/name] or [name]Sophie[/name] [name]Rebecca[/name], but [name]Sophie[/name] [name]Beckham[/name] is nice, too. [name]Sophie[/name] [name]Shepard[/name] is lovely!
Much, much, much prefer [name]Sophie[/name] [name]Beckham[/name] [name]Shephard[/name]. It’s a distinctive, interesting name; it’s not trendy like flash-in-the-pan [name]Addison[/name] ("[name]Madison[/name] without the M!" thousands of parents simultaneously cried), and it flows well.
If you consider the [name]Addison[/name], [name]Kate[/name] and [name]Shephard[/name] [name]Grey[/name]'s Anatomy problem, I think [name]Sophie[/name] [name]Beckham[/name] is even more clearly the top contender.
Definitely [name]Sophie[/name] – love that name. And I see what folks are saying about [name]Beckham[/name] because of [name]David[/name] [name]Beckham[/name], but honestly, it’s her middle name so most people won’t know it and if it’s connected to your family and honors someone or people in your family, that’s lovely. I vote for [name]Sophie[/name] [name]Beckham[/name]. If you were doing it because of [name]David[/name] [name]Beckham[/name], that would be an entirely different story, but you’re not. [name]Sophie[/name] [name]Shephard[/name] is beautiful. She’s a lucky girl. 
P.S. When I saw [name]Addison[/name] [name]Shephard[/name], the first thing I thought was also [name]Grey[/name]'s Anatomy. But overall, I just like [name]Sophie[/name] much better than [name]Addison[/name].
I’m not a fan of [name]Beckham[/name] or [name]Addison[/name], but for overall combo I would go for [name]Addison[/name] [name]Kate[/name].
I’m so jealous that [name]Beckham[/name] is a family name for you, I’d love to be able to get away with using it!
[name]Sophia[/name] [name]Shepard[/name] gets my vote, I love [name]Addison[/name] on a boy!
