Help with Elis siblings name😀

We are expecting our 2nd little boy come [name_u]August[/name_u] 16th😀 Our first little boy is [name_m]Eli[/name_m] [name_m]Aaron[/name_m]. We are torn between two names: [name_m]Isaac[/name_m] [name_m]Mark[/name_m], which we feel is a classic choice that compliments big brothers name nicely. Our other choice is Cainan [name_m]Mark[/name_m], which we feel is a little more outside of the box and unusual. Any advice is appreciated!

[name_m]Isaac[/name_m] [name_m]Mark[/name_m] has a nice sound to it, and it does go well with [name_m]Eli[/name_m] [name_m]Aaron[/name_m].

To be honest, I’m not really a fan of either in this case. [name_m]Isaac[/name_m] goes really well with [name_m]Eli[/name_m] but [name_m]Isaac[/name_m] [name_m]Mark[/name_m] sounds a bit jarring to me, with having similar a sounds in the middle and the same ending sound. Cainan is a bit out there compared to [name_m]Eli[/name_m], but sounds better with [name_m]Mark[/name_m]. Are you looking for suggestions for other first and/or middle names?

[name_m]Isaac[/name_m] [name_m]Mark[/name_m]
