We have two sons, first names are [name_u]Avery[/name_u] and [name_u]Owen[/name_u], they both have K middle names. I would love (potential) DS #3 to have a C middle name, so it kind of matches, sound-wise. I’m completely lost on a first name. It should match [name_u]Avery[/name_u] and [name_u]Owen[/name_u]. [name_f]Every[/name_f] name I come up with, DH vetoes! Any suggestions? We love [name_u]Cameron[/name_u], [name_u]Corey[/name_u], or [name_m]Cole[/name_m] for a MN.
Strong A in [name_u]Avery[/name_u]
Strong O in [name_u]Owen[/name_u]
Strong E - [name_m]Eli[/name_m], [name_m]Elijah[/name_m], [name_m]Ethan[/name_m],
[name_m]Eli[/name_m] [name_u]Cameron[/name_u], [name_m]Elijah[/name_m] [name_m]Cole[/name_m], [name_m]Ethan[/name_m] [name_m]Cole[/name_m],
[name_u]Avery[/name_u] and [name_u]Owen[/name_u] is a gorgeous sibset! Some suggestions for potential son number 3:
[name_u]Finley[/name_u]
[name_u]Flynn[/name_u]
[name_u]Quinn[/name_u]
[name_m]Asher[/name_m]
[name_m]Edison[/name_m]
[name_u]Emmett[/name_u]

Two syllable, common but not crazy overused, I wouldn’t repeat the first or last letters so that you get a unique but compatible name. I wouldn’t start or end the first name with k or c.
[name_u]Cameron[/name_u]
[name_u]Corey[/name_u]
[name_m]Cole[/name_m]
Consider the syllable count of your other sons middles. If they’re the same consider choosing a name that matches syllable wise as well, if they’re different consider choosing another different count name. Take into account how the other boys middles end, if they end the same do you want to choose another same ending, If they end different do you want something that ends different.
Consider all nanes obviously with your surname.
So thinking of two syllable boys names not ending in n or y sound or c/k sound…
Possibly
[name_m]Jacob[/name_m]
[name_u]River[/name_u]
[name_m]Forest[/name_m]
As examples
[name_m]Beckett[/name_m]
[name_m]Bennett[/name_m]
[name_m]David[/name_m]
[name_m]Daniel[/name_m]
[name_m]Hamish[/name_m]
[name_u]Harbor[/name_u]
[name_m]Liam[/name_m]
[name_u]Lawrence[/name_u]
[name_u]Michael[/name_u]
[name_m]Matthew[/name_m]
[name_u]Noah[/name_u]
[name_m]Peter[/name_m]
[name_m]Thomas[/name_m]
[name_m]Victor[/name_m]
[name_m]Vincent[/name_m]
[name_m]Wyatt[/name_m]
[name_m]Walter[/name_m]
[name_u]Avery[/name_u] and [name_u]Owen[/name_u] are so great together! I would use another vowel name:
[name_u]Ellis[/name_u]
[name_m]Isaac[/name_m]
[name_u]Elliot[/name_u]
[name_m]Ian[/name_m]
