[name_m]Hi[/name_m] there.
You did a great job the first five times. Here are my thoughts on lists for #6:
Boys-
[name_m]Eugene[/name_m]-I don’t mind this. It’s certainly different these days. It’s very kind sounding.
[name_m]Julian[/name_m]-This is at the very top of my personal boy list as well. I love it, & it’s perfect w/your crew. Smart, handsome, masculine yet not overly macho.
[name_u]Wallace[/name_u]-I don’t know that I care for this. It reminds me of a grumpy old man. Not like a sweet old man like [name_m]Eugene[/name_m] does. 
[name_u]August[/name_u]-Another awesome choice. Cute nns too if you’re into those.
[name_m]Alexander[/name_m]-I like this, & I think the style fits. [name_f]Do[/name_f] you like [name_u]Alex[/name_u]? It may be hard to avoid. Seems a little bland next to your kids’ names.
[name_m]Caspar[/name_m]-Ooh, thank you for spelling it this way. So much nicer than [name_m]Casper[/name_m], in my opinion. Really cool artsy name. I like it for you.
Well, I’m no help since I mostly like them all! My favorite is [name_m]Julian[/name_m]. I would consider nns that you may like or not like just in case like [name_u]Wally[/name_u], [name_m]Augie[/name_m], [name_u]Alex[/name_u] or [name_m]Cas[/name_m].
Three suggestions:
[name_m]Alistair[/name_m]
[name_m]Barnaby[/name_m]
[name_m]Oscar[/name_m]
Girls-
[name_f]Marianne[/name_f]-I’m not sure about this one. I like [name_u]Marian[/name_u] a lot said as one flow of [name_f]Mary[/name_f]-in. This spelling I’m not sure whether to say it like that or [name_f]Mary[/name_f]-[name_f]Ann[/name_f].
[name_f]Rosemary[/name_f]-I can’t get over the creepy movie here.
[name_f]Magnolia[/name_f]-Beautiful! Perfect for you.
[name_f]Penelope[/name_f]-I love this one as long as you don’t mind repeating initials w/sisters. Apparently it’s sort of popular, but that may not bother you. So many cute nns too.
[name_f]Josephine[/name_f]-Another beautiful choice.
[name_f]Hazel[/name_f]-This is nice. It doesn’t seem quite as dramatic (in a good way!) as [name_f]Philomena[/name_f] & [name_f]Cecilia[/name_f]. Pretty popular too.
I think I like [name_f]Magnolia[/name_f] best, but [name_f]Penelope[/name_f] & [name_f]Josephine[/name_f] are also two of my favorites. Close call!
And three suggestions:
[name_f]Louisa[/name_f]
[name_f]Millicent[/name_f]
[name_f]Romilly[/name_f]
[name_f]Hope[/name_f] this helps.
