This paper examines in some detail the relationship between Elizabeth Corbet Yeats and her brother, William Butler Yeats, pertaining to the activities of the Cuala Press which Elizabeth ran as the printer from 1902 (as the Dun Emer Press and then, the Cuala Press from 1908) while William was the editor, selecting and soliciting books. Their relationship, while stormy all-along, and determined by William’s authoritative editorial choices undermining his sister’s literary role, was, nonetheless, mitigated by William’s attribution of the key role as the printer and publisher to Elizabeth. The relationship was thus often ambivalent and elusive, like many such family ties, than has generally been acknowledged by scholars.
