Miss Roberts belonged to a Welsh family of great respectability. Her grandfather, who was a gentleman of good property, and served the office of High Sheriff for Denbighshire, North Wales, possessed the fine estate of Kenmell Park in that county, which was disposed of after his death to Colonel Hughes, the present Lord Dinorben, whose seat it continues to be. He had three sons, all of whom entered a military life, which seems to have had peculiar attractions to this gallant family. The eldest, the late General Thomas Roberts, raised a regiment, which became the 111th, and it is said he frequently officiated as Gold Stick in Waiting to George the Third. A son of General Roberts was aide-de-camp to Sir Arthur Wellesley in Portugal, was taken prisoner by the French, and detained during the war: he afterwards rose to the rank of lieutenant-colonel. The second son, Colonel David Roberts, of the 51st regiment, distinguished himself in the Peninsular war, having, on the 7th January, 1809, during Sir John Moore’s retreat, near the heights of Lugo, headed a party which repulsed the French Light Brigade, on which occasion his cloak was riddled with bullets, two of which passed through his right-hand, which was amputated. He was then a major, but afterwards commanded the regiment, in Lord Dalhousie’s brigade, and subsequently in Flanders, and was so seriously and repeatedly wounded, that his pensions for wounds amounted to L500 a year. Colonel Roberts was an author, and wrote, amongst other things, the comic military sketch called Johnny Newcome. The youngest son, William (the father of Miss Roberts), in the course of his travels on the continent, in early life, formed some intimacies at the Court of St. Petersburgh (to which he was introduced by the British Ambassador), and eventually entered the Russian service; he was made aide-de-camp to General Lloyd, his countryman, and served with great distinction in several campaigns against the Turks. He afterwards entered the British army, but had not attained a higher rank than that of captain (with the paymastership of his regiment), when he died, leaving a widow, a son (who died a lieutenant in the army), and two daughters.
Emma, the youngest daughter of Captain Roberts, was born about the year 1794. After the death of her father, she resided with her mother, a lady of some literary pretensions, at Bath. Though possessed of a very attractive person, though of a lively disposition, and peculiarly fitted to shine in the gayest circles of social life, her thirst for letters was unquenchable, and the extent of her reading proves that her early years must have been years of application.
