I love [name_m]Magnus[/name_m]! I’d say some nicknames for him could be [name_m]Sonny[/name_m] (nus [name_f][/name_f]- backwards) or [name_m]Mack[/name_m]? [name_m]Atticus[/name_m], [name_m]Malcolm[/name_m] and [name_m]Magnus[/name_m] sounds great. Some other suggestions;
[name_f][/name_f][name_m]Lachlan[/name_m] (Lockie), [name_m]Fletcher[/name_m] (Fletch, Flynn), [name_m]Callum[/name_m] (Cal), [name_m]Kenneth[/name_m] (Ken, [name_m]Kenny[/name_m], Kit), [name_m]Douglas[/name_m] (Doug, Dougie)
