Lucien Bazor Coin Engraver True Identity

I notice that there are several different name configurations for Lucien Bazor. 

On some African colonial coins I've seen Gabriel Bernard & Lucien Bazor as two different people. 

Then there is Gabriel Bernard Lucien Bazor as one person.

There is also Lucien Georges Bazor on some French coins. 

Anyone have a clue as to whether this is one person or multiple people.

Lucien Georges Bazor is the creator of a large number of coins. He signs his engravings L.Bazor (Lucien), G.B.Bazor (George Bernard) or sometimes G.B.L.Bazor (Georges Bernard Lucien).
