Yes, i do find [name_m]Jack[/name_m] a bit lacklustre, kind of like a sturdy, solid but unremarkable name, however[name_f][/name_f], it does have the benefit of being timeless, versatile and still energised rather than dated or heavily classic [name_f][/name_f]- and I’ve known [name_f][/name_f] quite a number of Jacks, and none of them disliked their name.
[name_f][/name_f]You could do something like [name_m]Ajax[/name_m] (nn Jack)?
[name_f][/name_f][name_m]Jack[/name_m] [name_m]Max[/name_m] is quite rhymey [name_f][/name_f]- maybe [name_m]Jack[/name_m] [name_m]Maxwell[/name_m]? [name_m]Jack[/name_m] [name_m]Magnus[/name_m]?
