South Carolina ? The Jamison family triplets are in the record book.

When the Elgin-born siblings entered the world on three separate days in 1956, it marked the longest recorded interval in the births of triplets. Today, their names – and their mother’s nearly 67 hours of labor – have been added to the Guinness World Records book.

“It was a long time that we were waiting for it,” Catherine Jamison Able, the second born of the trio, said of their addition to Guinness. “I wish my parents were here to enjoy the moment.”

Christine Berdeguez-Jamison was born Jan. 2, 1956, followed by her sister Catherine on Jan. 3 and their younger brother Calvin Jamison on Jan. 4.
