I think [name_m]Archer[/name_m] ‘[name_m]Archie[/name_m]’ is gorgeous with [name_f]Abigail[/name_f]. [name_m]Harrison[/name_m] would probably be my second choice and I don’t think [name_m]Davy[/name_m] makes either [name_m]Harry[/name_m] or [name_m]Archie[/name_m] unusable. I think [name_m]Sebastian[/name_m], [name_m]Hugo[/name_m], [name_m]Oliver[/name_m] or [name_m]Henry[/name_m] would also work really well.
[name_m]Hi[/name_m] there.
[name_f]Abigail[/name_f] nn [name_u]Abbie[/name_u] is cute! I have good friends w/an [name_u]Abbie[/name_u] (short for [name_u]Aberdeen[/name_u].). I really prefer that spelling.
Anyway, onto [name_u]Abbie[/name_u]'s brother!
Here are my thoughts on the list:
[name_m]Ethan[/name_m]-Meh, this is not my favorite either. It’s perfectly nice though. Is it your absolute favorite? If so, I’d go ahead & use it. Your dad will go over it when he meets his sweet little grandson w/the name [name_m]Ethan[/name_m] attatched.
[name_u]Logan[/name_u]-This is fine, but just way over done & not terribly exciting. Plus, the rhyming thing.
[name_m]Harrison[/name_m]-This is fun. Distinguished yet lovable. I agree that [name_m]Harry[/name_m] [name_m]Davy[/name_m] doesn’t sound great, but it’s fine if it’s just a nn. I also love the nn [name_m]Hank[/name_m] for [name_m]Harrison[/name_m].
[name_m]Archer[/name_m]-This is charming. [name_m]Archie[/name_m] & [name_u]Abbie[/name_u] are maybe kind of cutesy together, but not a deal breaker. I like [name_m]Archer[/name_m] way more than [name_m]Archibald[/name_m]. [name_m]Archibald[/name_m] always sounded weird to me. I just hear the bald part. [name_m]Archer[/name_m] is handsome & just the right amount of quirky.
[name_m]Benjamin[/name_m]-A handsome classic, although way over done.
[name_u]Ryan[/name_u]-Yeah, I feel like this is really 90s & kind of boring.
[name_m]Lachlan[/name_m]-Ooh, I like this. Sort of a different style than [name_f]Abigail[/name_f], but it’s not a problem. [name_m]Lachlan[/name_m] [name_m]Davy[/name_m] sounds great, & [name_m]Lachlan[/name_m] is very cool. It’s handsome, kind & sporty.
[name_m]Thomas[/name_m]-Good solid classic. I’m not a huge fan of [name_m]Tom[/name_m] or [name_m]Tommy[/name_m] personally.
My favorite may be [name_m]Lachlan[/name_m], but really none of them are bad.
[name_f]Hope[/name_f] this helps. 
Thanks so much for the detailed responses and poll. It has been so insightful. When you’ve been looking at names so long you lose objectivity. Appreciate the time!
My favourite is [name_m]Lachlan[/name_m] and it is wonderful with [name_m]Davy[/name_m]. I would suggest to maybe try to choose a first name that does not end in the ‘ee or ey’ sound with [name_m]Davy[/name_m] as it gets a bit rhymy.
