Hey Iowa! Question about US Navy WWII Vets who were Twins, from Roland, Iowa

I'm looking through a Time / Life Book my Mom bought me, 23 years ago, called......"Our Finest Hour". An AAAAWESOME book about the WWII generation in general. In it is a story and several photos on two twin boys, from Roland , Iowa, who were just 17 years old when they joined the Navy. I dug on the internet, trying to find out what became of them but found nothing. Just wondering if you knew anything on the History of these fellas. Their names were Harold and Harry Martinson.
