Francis Xavier Brady was born on March 29, 1857, in Buchanan Valley near Gettysburg, Pennsylvania,[1] to Samuel J. Brady and Margaret Goy.[2] His father was of Irish descent, while his mother was Pennsylvania Dutch. One of five children, he had three brothers and a sister who entered the Sisters of St. Joseph.[1] Francis decided to join the Society of Jesus, and entered the novitiate in Frederick, Maryland, on July 21, 1873. As part of his studies, he was sent to Woodstock College in 1876. After three years, he went to teach at Gonzaga College. He was then transferred to St. Peter's Church in Jersey City, New Jersey, in 1881, before returning to Woodstock in 1884 to complete his education.[3]
Because of his poor health, the Jesuit superiors decided to expedite his studies, and he was ordained a priest by Cardinal James Gibbons on August 28, 1886, at Woodstock College.[4]
