I am a IIIrd, the third person down my male line with the same first, middle, and last name

I'm the 5th with our exact initials, too

One time, while applying for college, I was told I'd already used my GI bill allotment back in '55. Uh..... That was grandpa, and he died over 30 years before I was born, how did you mix us up?!?!

(Also, I was never in the military and this was entirely irrelevant to me they just brought it up as something I couldn't do)
