Lee De Lange, one of their sons, told CNN affiliate KSFY
there was a divine quality to having both parents pass at nearly the same time.
"We're calling it a beautiful act of God's providential love and mercy," he said. "You don't pray for it because it seems mean but you couldn't ask for anything more beautiful."
Jeanette De Lange, 87 and suffering from Alzheimer's disease, died first at 5:10 p.m. Family gathered with her was reading the Bible at the time.
"We read Psalm 103. We didn't quite get done," said Lee De Lange. "She passed away very, very peacefully. Incredibly peacefully."
'Gone to heaven'
Lee said his brother told his father, 86 and fighting prostate cancer, "mom's gone to heaven" and that he didn't have to fight anymore. He could let go and join her if he wished, the son added.
Twenty minutes later, at 5:30 p.m., Henry De Lange did just that. His children remember him briefly opening his eyes and looking at his wife before he died.
Of course this isn't the first time that a married couple has passed away on the same day.
Earlier this summer George and Ora Lee Rodriguez
, married for 58 years, died a few hours apart at their home in San Antonio, surrounded by family -- and holding each other's hands.
