I am very fond of [name_m]Zachary[/name_m] [name_u]Owen[/name_u] because it seems like both names are something a boy could grow into. It has a very masculine ring to it, while still sounding cute for a little guy.
Also (sorry if this is over-stepping any boundaries!), I very much enjoy the combination [name_m]Zachary[/name_m] [name_m]Isaac[/name_m], mostly for the meaning. [name_m]Zachary[/name_m] sometimes being translated as “surviving” rather than “the [name_m]Lord[/name_m] has remembered” leaves the above combination meaning “Surviving Laughter,” which I find lovely. ([name_f]Hope[/name_f] that wasn’t rude… )
