William Cleffi, principal of Morris Knolls High School in Denville, N.J., said the number of twins scheduled to walk down the aisle Wednesday is only two sets short of a Guinness World Record, The (Newark, N.J.) Star-Ledger reported Tuesday.
"It's very unusual," Cleffi said. "We've had multiples before, but it's usually been two or three (sets)."
Cleffi and the graduating sets of twins said they did not realize exactly how many multiples were going to be graduating until early this year.
"We just knew that there were some twins, but we had no idea there were that many," said Ryan Leonardow, 18, who is preparing to graduate alongside his twin sister, Kaylen.
