This is our second boy and his brother is [name]Christopher[/name] (the third), so we are looking for a classic name to match. We are using [name]David[/name] (after my dad) as the middle name and we are trying to find a [name]German[/name] or English name…any suggestions??
I like [name]Dominic[/name] and [name]Christopher[/name] together but not sure about [name]Dominic[/name] [name]David[/name]
[name]How[/name] about [name]Christopher[/name] and
[name]Matthew[/name] [name]David[/name]
[name]Anthony[/name] [name]David[/name] - my favorite.
[name]Joseph[/name] [name]David[/name]
[name]Michael[/name] [name]David[/name] - popular but it’s still on the top of my list and I love it with [name]Christopher[/name].
[name]Nathaniel[/name] [name]David[/name]
[name]William[/name] [name]David[/name] - I love nn’s [name]Chris[/name] and [name]Will[/name]
[name]German[/name]:
[name]Frederick[/name] [name]David[/name]
[name]Henry[/name] [name]David[/name]
[name]Milo[/name] [name]David[/name]
English:
[name]Barnaby[/name] [name]David[/name]
[name]Everett[/name] [name]David[/name] (kind of V heavy, though)
[name]Harrison[/name] [name]David[/name]
[name]Jefferson[/name] [name]David[/name]
[name]Julian[/name] [name]David[/name]
[name]Sebastian[/name] [name]David[/name]
[name]Spencer[/name] [name]David[/name] (not the best flow…)
[name]William[/name] [name]David[/name] (I just saw that Disa suggested this…I love it!) 
Other origins:
[name]Benjamin[/name] [name]David[/name]
[name]Elliot[/name] [name]David[/name]
[name]Oliver[/name] [name]David[/name]
Good luck!
Some super suggestions above, but I’ll try to add some more.
From the [name]German[/name] Top 100:
[name]Robin[/name] [name]David[/name] (actually, on second thought, [name]Christopher[/name] and [name]Robin[/name] is a bit [name]Winnie[/name] the Pooh)
[name]Benedict[/name] [name]David[/name]
[name]Johann[/name] [name]David[/name]
[name]Maxim[/name] [name]David[/name]
[name]Bastian[/name] [name]David[/name] (I love this with [name]Christopher[/name]!)
[name]Jeremy[/name] [name]David[/name]
[name]Jonathan[/name] [name]David[/name]
[name]Anton[/name] [name]David[/name]
[name]Alexander[/name] [name]David[/name]
[name]Philip[/name] [name]David[/name]
[name]Felix[/name] [name]David[/name]
[name]Timothy[/name] [name]David[/name]
[name]Leon[/name] [name]David[/name]
I also like the sound of [name]Nicholas[/name] [name]David[/name], and think it goes well with [name]Christian[/name].
Good luck!
I know a family with three young boys named [name]Christopher[/name], [name]Alexander[/name] and [name]Nicholas[/name]. I love those names together. Each name is a classic, sounds strong, and is from the Greek language. Right now the boys at-home nicknames are [name]Christo[/name], [name]Alex[/name] and [name]Nico[/name]; only the oldest is in school and goes by his full name [name]Christopher[/name] there.
Best wishes!
