Gainsborough left two daughters, whose portraits he painted several times. The elder one, Margaret, did not marry; while the younger, Mary, was secretly wedded in 1780 to her father's friend, Johann Christian Fischer, the hautboy player. This marriage caused Gainsborough much trouble; he foresaw that the musician's irritability and eccentric behaviour on many occasions could not conduce to the happiness of his daughter; however, to quote his own letter to his sister, Mrs. Gibbon, "As it was too late for me to alter anything without being the cause of total unhappiness on both sides, my _consent_, which was a mere compliment to affect to ask, I needs must give." The father's foreboding was only too fully justified; the union turned out very unhappy from the first, and within a year or so husband and wife separated. Both sisters were mentally deficient, and their aberrations increased with age to the point of total derangement. Mary, soon after her marriage, became subject to wild hallucinations, "perhaps the most reasonable" (as Fulcher puts it) being that the Prince of Wales was pursuing her with his love. After her mother's death she went to live with her sister, whose mental condition was even worse than her own; they would receive no visitors who did not belong to the nobility, so that many who wished to gain admittance to the house were obliged to assume titles which they did not possess. Margaret died about 1824, and Mary a year or two later; before her death she insisted on presenting to the king the portrait of Fischer, painted by her father at Bath about forty years before; this portrait is now in the Royal Collection. Of Gainsborough's personality and character much has no doubt been gathered from the preceding pages. His physical appearance is familiar from his own portraits of himself, and from that which Zoffany painted of him. He was handsome, tall and strong, with large features and a broad if not very high forehead; the small eyes are quick and observant, the mouth sensitive and rather undecided. In the choice of his friends he attached little importance to breeding and none to social position; he was generous and open-handed to all, with money to his relations and often indiscriminately with his works to friends or mere acquaintances: on one occasion he gave his picture of the "Boy at the Stile" to Colonel Hamilton (equally well known at the time as an amateur violinist and a gentleman pugilist) for having played him a solo on the violin; to Wiltshire, the carrier who took his pictures from Bath to London, and who refused to take payment in money from the artist, he presented many valuable landscapes.
