I would now take the liberty of asking C. to explain the following extract from Souverains du Monde, not finding any particulars respecting the first marriage here alluded to in those books to which I have been able to refer:—

"Les enfans naturals du Roi Jaques II. sont 1.... 2.... 3....

"4. Catherine Darnley, mariée en premières nôces avec Thomas Wentworth, Baron de Raby; et en secondes nôces, en 1699, avec James, Comte d'Anglesey. Elle est morte en 1700. Sa mère étoit Catherine Sedley, Comtesse de Dorchester, Baronne d'Arlington.

"5. N. mariée avec le Duc de Buckingham le 27 Mars, 1706."

You will observe that my former inquiry referred to the daughter above stated as the fifth child.

It is plain that the compiler of Les Souverains du Monde is in error in making the wife of the Earl of Anglesey a distinct person from the wife of the Duke of Buckingham.

Who was the wife to the Thomas Wentworth here mentioned? and, if a natural daughter of James II., I should be glad of the following particulars,—the names of her mother and self—the dates of her birth, marriage, and death—and the date of the death of her husband.

I must apologise for trespassing thus at length upon your space.

F. B. RELTON.
