your thoughts on these two names together?

I think they sound fine together
If you and DH love Archie go for it it's really your opinions that count when it comes to it.

I like Archie and Acher, and think both go great with Charlie. If you love Archie then go for it.

[Daydream Believer]

I like them together too

LOOOOOVE THEM - totally go for it! You'll regret it if you 'play it safe' and dont go with what you love in your heart of hearts! (I played it safe and wish I hadn't!)

I think that they sound great together. I also like the names Archer and Oscar, you have choosen nice names .

I say it's a win. Go with Archie. Cute.

The issue you would have is if you go for a number 3, then a non "ie" name would be the odd one out...
