Everybody is just making up names like (Ferbenstein and ferbert) but I know for a FACT it is: Frank.Here is what I know:
F=Frank
E=England (Canada is actually apart of England and that is where they came from)
R=Reg (His grandpa)
B=British (Because his ascent)

That is why he is called Ferb.he is just embarresed because his names don't match.

does someone else knows something else??

It is really Frank.

WUT????

Is that for a fact or was it jest a theory? I don't quite think that it matches up XD Maybe they'll reveal it one day. It also doesn't quite make sense how that would connect... I mean, the F standing for that and all.

I always thought it was Frank... *shrug*

his real name is thomas brodie

I heard his name is Ferbucus/Ferbuscus

It's Frank :D

in 1 episode phineus calls ferb ferboush or something... he says ferb-ouushhh

I think it' s Ferbaius

I'm betting on Frank. The guy who's nickname is Ferb (they named the character after him)'s real name is Frank.

Ferbisson I kno
