I just named my last one "Commander", so that it would actually make sense when that's what everyone called him.
So his full name with rank is Commander Commander Shepard? :-D Love it! Kinda like when people put a "the" infront of something with The already in its name, like The "Los Muertos"
Give him a name that means something to you, or don't give it much thought. It has no bearing on any aspect of the game whatsoever, except for the player to identify the save games. Anyway, here are some suggestions:
- Default Shepard
- Generic Shepard
- Paragon Shepard
- Shepard Shepard
- Rocky Balboa Shepard
- Steven Shepard (Like Steven Segal only with body armour and biotics)
Alternatively, consider something exotic, such as Mikhail, Piotr, Jean-Paul, Marco, etc. But most importantly, play Vanguard because they rock Mass Effect.

I downloaded an ME1 save to have an ME2 playthru with particular choices made. His name was "Donutsftw Shepard". I did change it of course.
