Is Ellis from blazing angels the same Ellis from left for dead 2

yes i think they had the same idea

ellis from blazing angels in left for dead 2
they are both mechanics they both sound the same and they have both flown a plane as he says in left for dead 2 in the parish chapter 4 he will only say this when a plane bombs you so you have to wait

so i think he is from blazing angels yet he was alive in the london blitz which would make him old hes still young a mestiry we will never solve
