The unsatisfying answer to the title of this post is that nobody knows for sure. To quote one Nicholas scholar, “We can grant a bishop of that name who had a great impact on his homeland. We can also accept December 6 as the day of his death and burial. These are all the facts we can hold to. Further we cannot go.” (Gustav Anrich, quoted by Charles W. Jones in Saint Nicholas of Bari, Myra, and Manhattan).
