If you compare all details of both Julius Kingsley and Lelouch vi Britannia's Profiles, you'll see that there is only 1 deviation: Their Birth Date.

They both share the following aspects:

Black Hair. Purple Eyes, Flamboyant Arrogance, Voice, Overall Appearance.

The only difference is that Julius Kingsley is reported to be 1 year older than Lelouch, which could easily be another Memory Implanted into Lelouch's head, as a part of Kingsley's persona.

Lelouch vi Britannia and Julius Kingsley are The Same Person. I'm 99.99% Sure of this (The 0.01% being the unlikely situation of him being a Clone, like Nightmare of Nunally's Rolo vi Britannia)
