I don’t think we’ll be using it, so this is most for fun/curiosity but is there any full forms for [name_m]Reggie[/name_m] that’s not [name_m]Reginald[/name_m] or [name_f]Regina[/name_f]?
Sorry if some of these are stretchy…
[name_m]Peregrine[/name_m] (Peregrine)
[name_m]Regis[/name_m]
[name_m]Remington[/name_m]
[name_f]Ginevra[/name_f] (Ginevra)
[name_m]Algernon[/name_m] (Algernon)
Regulas
[name_m]Roger[/name_m]
[name_f]Regan[/name_f] or [name_f]Reagan[/name_f] maybe? Obviously the pronunciation is different but “reg” is right there in the name! Same with [name_m]Gregory[/name_m].
I also think [name_m]Roger[/name_m] is a fantastic suggestion above!
[name_f]Regenia[/name_f]
