Sirius' Name

On a slightly different note on Sirius' name, I just made the connection between Sirius the character and Sirius the dog of greek mythology.  Which explains his animagus transformation.  I'm attempting to find a link between Harry and his Sirius, and the Greek Sirius and his masters, but so far it evades me.
 
Oh, and my apologies if this has already been brought up a thousand times and ripped apart, I'm rather new.
