Found this in my daily searches. Have not found out which son it is but sure looks like his dad.
Coxswain Amin Isbir KIA - June 6th, 1944, Normandy France
Apparently he was a special guest at the 2006 Battle of the Bulge event in Ft. Indiantown Gap. Any re-enactors here attend that event? According to the source, he was wearing his father's uniform. Here is a very short video clip
