mrtn, at the grandparent level, the youngest to pass was 74 - paternal grandfather.
He was born a bluebaby.
He was shot in Germany in 1916.
He went back to the battle & got hit with a mortar in '18 - he was placed with the dead on that day.
They told my grandmother she was crazy to marry him in '23 - he was only gonna live 5 years.
He met all his grandchildren!
He died 50-1/2 years to the day after the WW1 medic gave him up for dead.
The other 3 totalled 274 years...
