Two Autograph Letters Signed (the first '(Hon) Donough O'Brien') from the genealogist Hon. Donough O'Brien, fourth son of Lord Inchiquin, to the ghost hunter Elliott O'Connell, the first regarding a genealogical table, the second arranging to meet.

Letter One: 1p., 12mo. Signed '(Hon) Donough O'Brien'. Good, on aged paper, with a couple of short closed tears at head. Addressed to 'Elliott O'Connell Esqre of The Red House, Guilsborough, Northants.' He is sending him a copy of his 'Genealogical Table of the Princes of Ireland', 'in a cardboard-roll to see': 'The descents are from the Common Ancestor, Milesius, King of Spain and Ireland'. The price is two pounds, and he believes that 'it is the first time that the 23 lines have been set out on one Chart and in their appropriate places of Geniture, and over so distant a period of time'. Letter Two: 1p., 12mo. Simply signed 'Donough O'Brien'. In fair condition, on lightly aged and ruckled paper. 'Certainly I remember meeting you. I am making a note that you will be at 49 Gros. Str from 29 Apr to 13 May, & if I am in town will hope to see you.' He explains his usual movements, suggesting that they 'meet by telephone when I'm up'.
