[1] Concanen: Matthew Concanen, a miscellaneous writer, was born in Ireland about the end of the seventeenth century. He early went over to London, and commenced writing as an advocate of the Government, and for the Newspapers, especially for the Speculatist. His brilliant abilities recommended him to the Duke of Newcastle, who in 1732 procured for him the Attorney-Generalship of Jamaica, a post he held for nearly seventeen years. He published a volume of miscellaneous poems, original and translated, and was the author of a comedy, Wexford Wells. Concanen died in London in 1749. Allibone says of him:—"He is principally remembered through the celebrated letter of Warburton concerning him, and by his position in the Dunciad—his reward for attacking Pope."

[2] MacConceannain: By some genealogists this sirname is derived from the Irish Conganan ("conn:" Irish, a man's name; "gan" without; "an," a lie), meaning "Conn the speaker of truth."

[3] Davie: This name has been modernized Davies and Davis.
