Yeats's father, John Butler Yeats, was a barrister who eventually became a portrait painter. His mother, formerly Susan Pollexfen, was the daughter of a prosperous merchant in Sligo, in western Ireland. Through both parents Yeats claimed kinship with various Anglo-Irish Protestant families who are mentioned in his work. Normally, Yeats would have been expected to identify with his Protestant tradition—which represented a powerful minority among Ireland's predominantly Roman Catholic population—but he did not. Indeed, he was separated from both historical traditions available to him in Ireland—from the Roman Catholics, because he could not share their faith, and from the Protestants, because he felt repelled by their concern for material success. Yeats's best hope, he felt, was to cultivate a tradition more profound than either the Catholic or the Protestant—the tradition of a hidden Ireland that existed largely in the anthropological evidence of its surviving customs, beliefs, and holy places, more pagan than Christian.
