When he was eight years old, his family moved to Wexford, where his father, James McGee, was employed by the coast guard. In Wexford he attended a local hedge school, where the teacher, Michael Donnelly, fed his hunger for knowledge and where he learned of the long history of British rule and Irish opposition, including the more recent uprising of 1798. In 1842 at age 17, McGee left Ireland with his sister due to a poor relationship with their stepmother, Margaret Dea, who had married his father in 1840 after the death of his mother 22 August 1833. In 1842 he sailed from Wexford harbour aboard the brig "Leo", bound for the United States. On the "Leo" he wrote many of his early poems, mostly about Ireland. He soon found work as assistant editor of Patrick Donahoe's "Boston Pilot", a Catholic newspaper in Boston, Massachusetts. He specialized in articles expounding the movement for Irish self-determination led by Daniel O’Connell. He became the lead editor in 1844, While writing widely as well on Irish literature and politics. He advocated the union of Canada into the United States, saying, "Either by purchase, conquest, or stipulation, Canada must be yielded by Great Britain to this Republic."
