Though many details about his early life are in dispute, scholars agree that Arnold was born in New York City and that his father may have been the Reverend George B. Arnold. The family relocated to Illinois and then to Monmouth County, New Jersey where Arnold enjoyed a country upbringing. Though he apprenticed himself to a portrait painter in New York in 1852, Arnold soon determined that literature would be his true calling.
Born in County Cork and raised primarily in Limerick, Ireland, Fitz-James O'Brien moved to New York City in 1852. Descending from an Anglo-Irish landholding family, O'Brien received his inheritance (estimated at £8000) at about the age of 21. Between 1849 and 1851, it is believed that O'Brien edited a failed literary magazine called The Parlour Magazine of the Literature of All Nations and squandered his inheritance (Wolle 21). Leaving England almost penniless, O'Brien immigrated to America and made the U.S.
Born in rural Chester County, Pennsylvania, Bayard Taylor's ancestors were Quakers with ties to William Penn. Taylor began writing poems as a child and served an apprenticeship at the West Chester Village Record. Rufus Wilmot Griswold, editor of Graham's Magazine, encouraged Taylor to publish his first volume of poetry, Ximena (1844). He traveled to Europe soon after; before leaving, he visited New York and met Nathaniel Parker Willis, a frequenter of Pfaff's and an admirer of Edgar Allan Poe.
