Roland Davis and Lena Henderson, both 85, got hitched as teenagers and divorced 20 years and four children later.
Their youngest daughter, Renita Chadwick, herself a grandmother, said: “We are all so ridiculously excited. We’re like little children again.
“It’s every child’s dream, every child who has ever been in a family where divorce has occurred, that your parents would come back together.”
The couple met as teenagers in Chattanooga, Tennessee, and were married by a justice of the peace.
This time around, a church wedding is planned, in Buffalo, New York state, followed by a reception at a local restaurant.
“I’m just happy that we’re here,” said Mr Davis, who recently moved to Buffalo from Colorado following the death of his second wife in January. .
Mr Davis proposed to Mrs Henderson, who is also widowed after re-marrying, over the phone around Easter and she accepted, even though they hadn’t seen each other since a family funeral in 1996.
Before that, the two hadn’t been face-to-face since splitting up in 1964, though they had stayed in touch and kept up with each other’s lives through the children.
Their oldest daughter, Johnnie Mae Funderbirk, had been urging her father to return to New York since his wife’s death.
“I had always kind of had that in mind, mostly because of the children,” he said. “You never forget someone that you cared for at one time or another.”
