The Admiral had been round the world with Anson, had been wrecked on the coast of Chili, and had published a narrative--"my granddad's narrative"--of his hardships and adventures. He had later been sent round the world on a voyage of discovery on his own account, but had discovered nothing in particular. Finally he had fought, not too successfully, against d'Estaing in the West Indies, and had withdrawn to misanthropic isolation. His son, Captain Byron, of the Guards, known to his contemporaries as "Mad Jack Byron," was a handsome youth of worthless character, but very fascinating to women. His elopement, while still a minor, with the Marchioness of Carmarthen, was one of the sensational events of a London season. Lady Carmarthen's husband having divorced her, Mad Jack married her in 1778. They lived together in Paris and at Chantilly--prosperously, for the bride had £4000 a year in her own right. A child was born--Augusta, who subsequently married Colonel Leigh; but, in 1784, his wife died, and Captain Byron, heavily in debt, was once more thrown on his own resources. He returned to England to look for an heiress, and he found one in the person of Miss Gordon of Gight, whom he met and married at Bath in 1786. The fortune, when the landed estates had been realised, amounted to about £23,000; and Captain Byron's clamorous creditors took most of it. A considerable portion of what was left was quickly squandered in riotous living on the Continent. The ultimate income consisted of the interest (subject to an annuity to Mrs. Byron's grandmother) on the sum of £4200; and that lamentable financial position had already been reached when Captain and Mrs. Byron came back to England and took a furnished house in Holles Street, where George Noel Gordon, sixth Lord Byron, was born on January 22, 1788. There we have, in brief outline, all that is essential of the little that is known of Byron's heredity. If it is not precisely common-place, it is at least undistinguished. No one can ever have generalised from it and said that the Byrons were brilliant, or even--in spite of the third Lord's conscientious attempts at versification--that they were "literary." A far more likely generalisation would have been that the Byrons were mad.
