An Illinois couple married for 69 years have died with an hour of each other, family members tell US media, the BBC reports.

Isaac Vatkin, 91, was holding the hand of his wife Teresa, 89, as she succumbed to Alzheimer’s disease on Saturday, the Daily Herald reported.

Isaac died 40 minutes later. Family members said they took comfort in knowing they were together at the end.

“You didn’t want to see them go,” said grandson William Vatkin, “but you couldn’t ask for anything more.”

“Their love for each other was so strong, they simply could not live without each other,” said daughter Clara Gesklin at the couple’s joint funeral.
