My paternal grandfather had 7 siblings. All 8 of them were Air Force. 4 were pilots. 2 of the pilots died in combat. One Korea and 1 Vietnam. One great uncle( the oldest) was a nuclear engineer. He drafted plans for the nuclear bomb that was dropped on Nagasaki and was part of the crew that delivered the plans to the president and congress to show them progress/explain it. At his funeral( I was 14 so 20 years ago) were generals and pentagon employees who had worked with him. They spoke highly of him during speeches they gave at his funeral
his cancer was determined to have been caused by heavy metals and radiation( he was old as heck then so who knows what really killed him as he beat cancer 3 times). His wife died of same type cancer 20 years earlier. He lost a son 3 months after birth due to birth defects and leukemia they said were caused by his heavy metal exposures at oak ridge
His two daughters and one grandchild also died from cancer of same type in there mid life determined to be due to his service at oak ridge per the oncologist and researchers.
Talk about sacrifice. His lineage laid a heavy toll
