Apart from publishing contributions under different versions of his own name in English and Gaelic and under abbreviations, Ruaraidh Erskine was also likely the writer behind a number of pseudonyms. Those that were used for several contributions are treated separately (‘Conal Cròbhi’, ‘H. M.’, ‘Q. E. D.’), the ones below were only employed once. The provisional attribution is based on style and topics, but evidence suggesting a different authorship may yet come to light.
