Dr. Edmund Bailey O’Callaghan was born at Mallow, near Cork, Ireland in 1797. He studied medicine in his native country and in Paris, and came to Canada in 1823. He took an interest in politics on the patriots’ side and fled to America settling in Albany in 1837. He worked in American History, especially with colonial New York history. The last decade of his life was spent in New York City where he died on May 29, 1880.

The catalog of his library (Google’s Harvard copy is annotated by Luther S. Livingston) sold in December, 1882, & compiled by E. W. Nash. “The best working library of Americana in general, and New York Americana in particular ever offered at public sale.”
