Do you have relatives who fought during D-Day?

[Letum]

My Grandfather on my mother's side was a Higgins Boat (or some other landing vessel) Pilot
(in the Army, not R.Navy). His brother was in Montgomery's staff in the invasion.
My Great Grandfather on my fathers side was a Colonel at the time (and had been since
WW1), but did not take a active part in the invasion due to his age. Apart from that, I
am not sure what he was doing at the time.
My Great Grandfather's brother was unable to attend the second world war at all due to
posthumously wining the VC in the previous world war.

I don't know about my Grandfather on my fathers side, but he was in the Army at the time
with rank.

I am the first in over 5 generations on my father's side to fail entrance to the Army.
