I found an obituary for Irving.
"PETERBOROUGH -- Irving "Nick" Eaton Nichols, 86, died Nov. 5, 2009, at Monadnock Community Hospital, after an extended illness with cancer.
He was born Nov. 25, 1922, in Boston, to Charles Eaton and Gladys (Edwards) Nichols. He attended Massachusetts State College at Amherst, graduating in 1944 with a bachelor's degree in animal husbandry. He was a U.S. Navy veteran of World War II.
In 1946, he moved to Peterborough to work for American Guernsey Cattle Club, retiring in 1982 as superintendent of the herd register department.

He served on the board of directors of Monadnock Country Club, Scott Farrar Home, Visiting Nurse Association, and Boy Scouts of America.
He was a lifelong Red Sox fan and an avid golfer. In 1988 he co-founded a junior golf program, which has introduced hundreds of 3rd-through-6th grade children to the game.

Based on the obituary, his birth year was 1922 not 1923.
I hope this helps.
