Leighton M. O'Connor

Leighton Michael O’Connor, 81, of Manchester, New Hampshire died peacefully at home with his wife by his side on Wednesday, May 14, 2025.

Leighton was born on July 3, 1943 to Joseph and Shirley (Wiggin) O’Connor in Peabody, Massachusetts. He attended Beverly schools, graduating from Beverly High School. He later went on to study finance at Babson College earning his MBA.

After college, he worked in school business administration for various school districts in Maine, New Hampshire, Massachusetts, Rhode Island and Florida. His passion for the outdoors - camping, bike riding, kayaking, x-country skiing, hiking and fishing kept him busy throughout his life. He enjoyed long Jeep rides through the notches of NH, down to the Keys, or to the coast for Ipswich fried clams.
