It was in Titusville that Nock met Agnes Grumbine, and they were married April 25, 1900. They had two sons: Samuel Albert, born in 1901, and Francis Jay, born in 1905. Nock left his wife soon thereafter, and never remarried. His sons grew up to become college teachers. Meanwhile, Nock was called to Christ Episcopal Church, Blacksburg, Virginia, and then to St. Joseph's Church in Detroit.
It was during Dr. Nock's rectorship that the choir was first vested, the Women's Auxiliary reorganized, St. James Guild formed, and the Willing Workers started their helpful work for the aged and infirmed clergy of the church.
In 1909, he seemed to have experienced a crisis of faith. "My life was detached, untouched and colorless," he later told Ruth Robinson. Nock embraced ideas of crusading economic reformer Henry George. George's philosophy was the philosophy of human freedom, he believed that all mankind are indefinitely improvable, and that the freer they are, the more they will improve.
Nock quit the clergy to become an editor of American Magazine, launched by editors and writers who had a falling out with S.S. McClure, the pioneering muckraking publisher. Nock worked at American Magazine for four years. He wrote articles advocating a single tax on land and he approved Canada's policy of having government own vast acreage. He befriended the former Toledo mayor and aspiring scholar Brand Whitlock, who later wrote a biography of the Marquis de Lafayette. He spent time with the likes of muckraking journalists Lincoln Steffens and John Reed. He honed his writing. "My stuff is good enough, perhaps, and surely better than five or six years ago, but it still sounds as though it was written from a seat in the grand stand." he wrote Ruth Robinson.
Two years before he died, Dr. Nock's autobiography " Memoirs of a Superfluous Man" was published. In the preface, he wrote, "Personal publicity of every kind is utterly distasteful to me." Indeed, he was a private man.
Albert Jay Nock passed away on August 19, 1945 at the home of Ruth Robinson in Wakefield Rhode Island. He was laid to rest at Riverside Cemetary in Wakefield, R.I.
