Diary entry in London.2

From the diaries of Mr Justice Robert Day of Kerry :-
"Mrs Day and I devote the forenoon to visiting Archdeacon Pott at Kensington, the Pattersons and poor Maria Gribble who I fear is in a very critical health; & the Evening to a very agreeable dinner party at Henry Grattons, 22 Bentinck St.- The Pott family are  gone to Exeter, of which Diocese he is Chancellor, and I learn at the house that Mr. Salmon, married to the Archdeacon's and my niece (Sam Pott's daughter) and who returned last winter with a shattered constitution from India, has just died"

Research Note :-
1. "Archdeacon Pott" was Joseph Holden Pott, 1759-1847, the son of Percivall Pott the surgeon, and he was appointed Canon and Chancellor of the diocese of Exeter in 1826. He never married.
2. Any niece of the Archdeacon would have to be the daughter of one of his siblings.
3. "Sam Pott" was in fact Samuel Potts who married Elizabeth Pott. She was the daughter of Percivall Pott, the surgeon, and the sister of Joseph Holden Pott. Therefore Samuel Potts was the brother-in-law of the Archdeacon, Joseph Holden Pott.
4. Any daughter of Samuel Potts would be the niece of Joseph Holden Pott.
5. Therefore, as the first Mrs Day, Mary Day née Potts, was not the daughter of the surgeon or the sister of the Archdeacon, and as Robert Day states that the daughter of Samuel Potts was his niece as well, this diary entry implies that his wife Mrs Day née Potts was the sister of Samuel Potts.

Memorial or Grave Stone in Ireland, Dublin, Monkstown Parish Church.1,5

Mural tablet erected by his widow

Died in Ireland, Loughlingstown.1,6

From the Kerry Evening Post :-
"'The good old Judge', as in the language of popular affection we have been accustomed to hear him spoken of, is no more! The kind relative, the true and steadfast friend, the benefactor of the poor, and the refuge of the distressed and the afflicted, has at last given up his spirit into the hands of the Judge of all flesh. It is not for us to do adequate justice to the many virtues of a character ever regulated by genuine Christian principles, and whose heart was the chosen abode of the most exalted philanthropy. Of his character as a Judge of the land for many years, the history of his country will speak. His decisions were those of justice tempered by mercy; and many a trembling wretch was rescued from ignominious death and reserved for repentance and forgiveness. As a kind, indulgent landlord, none stood higher in the estimation of the public, or in the affection of his tenantry, who, with his highly respectable and numerous relatives and friends, will never cease to revere his memory, Of him it may be truly said 'he never made an enemy, never lost a friend'."
