I’m fairly sure I know what I would name another boy, but I thought I would give you all the opportunity to weigh in (seeing as I already posted my girl list). I have a son already, named Liam. Surname is an Irish Mack name. Options:
Rafferty (my fave)
Ronan
Rowan
Jasper
August “Gus”
Ethan
Evan
Jack
Griffin
Malcolm
Alasdair “Alec”
Flynn
Finlay
Finn
Edit: middle name will be Kenneth
[name_m]Rafferty[/name_m] [name_m]Jack[/name_m]
If [name_m]Rafferty[/name_m] is your favorite, go with it! [name_m]Rafferty[/name_m] [name_m]Kenneth[/name_m] is very handsome and makes a great brother for [name_u]Liam[/name_u].
[name_f]My[/name_f] other favorites with [name_u]Liam[/name_u] would be [name_m]Ethan[/name_m], [name_u]Evan[/name_u], [name_m]Jack[/name_m], and [name_u]Finn[/name_u]!
I love [name_u]Finn[/name_u], [name_u]Flynn[/name_u], [name_m]Ethan[/name_m], [name_m]Jack[/name_m], and [name_u]Griffin[/name_u] with [name_u]Liam[/name_u]!
[name_m]Rafferty[/name_m], [name_m]Ronan[/name_m], [name_u]Rowan[/name_u], [name_u]August[/name_u], [name_u]Griffin[/name_u] & [name_u]Flynn[/name_u] are so lovely!
With big brother [name_u]Liam[/name_u], I think [name_m]Rafferty[/name_m], [name_u]August[/name_u] & [name_u]Griffin[/name_u] work best
With mn Kenneth; [name_m]Rafferty[/name_m], [name_m]Ronan[/name_m] & [name_u]Rowan[/name_u] wink best
[name_m]Ronan[/name_m], [name_u]August[/name_u], [name_m]Ethan[/name_m], [name_m]Jack[/name_m], [name_m]Alasdair[/name_m], [name_u]Flynn[/name_u], [name_u]Finlay[/name_u] and [name_u]Finn[/name_u] all fit beautifully with [name_m]Kenneth[/name_m] 
[name_u]Love[/name_u] [name_m]Rafferty[/name_m], [name_u]Jasper[/name_u], [name_u]August[/name_u], [name_m]Jack[/name_m] and [name_u]Flynn[/name_u]. All go brilliantly with [name_u]Liam[/name_u]!
[name_u]Finlay[/name_u] and [name_u]Finn[/name_u] are great too and very much suit [name_u]Liam[/name_u].
With [name_u]Liam[/name_u] I like [name_u]Rowan[/name_u], [name_m]Ethan[/name_m], [name_u]Evan[/name_u], [name_m]Jack[/name_m], [name_u]Flynn[/name_u], and [name_u]Finlay[/name_u]. I think out of those, [name_m]Jack[/name_m] and [name_u]Finlay[/name_u] go best 
[name_m]Hi[/name_m] again!
Here is my favorite to least favorite from this list:
Finn-I love the simplicity & charm of just [name_u]Finn[/name_u]. It’s sporty & spunky & sleek. Simple & well known, but not too popular. And obviously perfect w/Liam & a [name_u]Mack[/name_u] ln.
Finlay-It’s kind of annoyingly popular for girls, but I find it so handsome & adorable on a boy.
Ronan-I love this. It’s a great balance of sweet & strong. Simple but not popular. And Gaelic!
Jack-I love the simplicity & timeless vibe of this one. Really nice w/Liam.
[name_u]August[/name_u] ‘Gus’-Very handsome & [name_u]Gus[/name_u] is sweet & old fashioned.
Rafferty-I like it. I like it mainly for the nn [name_u]Rafe[/name_u]. It sounds great & w/a ‘Mack’ ln. It’s really different. Maybe not too complicated?
Rowan-I think it’s sweet & I like the nature-y -ness of it. [name_m]Ronan[/name_m] is a bit less common though, but they’re both good.
[name_m]Alasdair[/name_m] ‘Alec’-I 've never thought of [name_m]Alec[/name_m] as a nn for [name_m]Alasdair[/name_m]. I really like [name_m]Alec[/name_m], & it barely makes sense as a nn for [name_m]Alexander[/name_m], but I like this better! [name_m]Alasdair[/name_m] is a little complicated, but cool & smart anyway.
Flynn-I like it. I don’t know why I don’t like it nearly as much as [name_u]Finn[/name_u].
Malcolm-I think that it’s a really cool strong name. It may be too much w/a [name_u]Mack[/name_u] ln, but maybe not.
Evan-I love the name [name_m]Ewan[/name_m], so I should like this. But I just don’t for some reason. Maybe it feels too 90s?
Jasper-I really like [name_m]Casper[/name_m], but can’t get into this one. It feels goofy to me for some odd reason.
Griffin-I don’t like it much, because it reminds of the word gruff.
Ethan-It’s totally fine. It just feels a bit bland & over done. I don’t mind a popular name like [name_m]Jack[/name_m] or [name_u]Liam[/name_u] for that matter (love [name_u]Liam[/name_u], actually!). But [name_m]Ethan[/name_m] just doesn’t sparkle.
[name_f]Hope[/name_f] this helps.
Either [name_u]Rowan[/name_u] or [name_u]Flynn[/name_u] gets my vote!
You have a dreamy list!!
[name_m]Rafferty[/name_m] is beautiful! So rugged and lovely
[name_u]Jasper[/name_u], [name_u]August[/name_u] and [name_u]Evan[/name_u] are beautiful with [name_u]Liam[/name_u] too
Aw thank you!
With big brother [name_u]Liam[/name_u] I am really loving
[name_m]Alistair[/name_m] “Alec” [name_m]Kenneth[/name_m] M…
[name_u]Evan[/name_u] [name_m]Kenneth[/name_m]
[name_m]Rafferty[/name_m] [name_m]Jack[/name_m]
I love [name_m]Malcolm[/name_m] and [name_m]Ethan[/name_m].
