Mather Brown, was a grandson of Rev. Mather Byles (1). His mother was Elizabeth, born in 1737, who married in 1760 Gawler Brown and died in 1763.
Mather Brown went to Europe in 1780, with a letter of introduction from his grandfather to Harrison Gray, Esq., London, a firm friend of the family. Mr. Copley had likewise been intimate with Dr. Byles before he left Boston. He also gave him a letter addressed by the old patriarch "To Mr. Copley in the Solar system." In a letter dated Paris 23, 1781, he writes: "Dr. Franklin has given me a pass, and recommendatory letter to the famous Mr. West. He treats me with the utmost politeness; has given me an invitation to his home. I delivered him my grandfather's message, he expressed himself with the greatest esteem and affection for him, and has since introduced me at Versailles, as being grandson to one of his most particular friends in America."
In his first letter from London, 1781, he writes: "In consequence of the recommendation of Dr. Franklin, who gave me letters to his fellow townsman, the famous Mr. West of Philadelphia, I practice gratis with this gentleman, who affords me every encouragement, as well as Mr. Copley, who is particularly kind to me, welcomed me to his home, and lent me his pictures, etc. At my arrival Mr. Treasurer Gray carried me and introduced me to Lord George Germaine." In a letter in 1783 he wrote: "I have exhibited four pictures in the exhibition; the king and queen were there yesterday." In 1784: "I have painted several Americans. Yesterday I had two pictures shown his royal highness, the Prince of Wales. They were carried to the palace by his page. He criticised them, and thought them strong likenesses. I believe I never told you that the king knew a picture of mine in the last exhibition, of the keeper of Windsor Castle, and took particular notice of Mr. Gray's picture; asked him who it was, and who did it, and what book he had in his hand. Mr. West told him it was the treasurer of Boston painted by his pupil, a young man, Mr. Brown of America. The king asked him what part. He told him Massachusetts." In 1785 he writes: "Among other great people I have painted, Sir William Pepperell and family, and Hon. John Adams, ambassador to His Britannic Majesty. On the 20th of June, I had the honor to be introduced to the Duke of Northumberland at his palace; his Grace received me with the utmost politeness."
Mather Brown became afterwards artist to the king, a worthy successor to Copley. And thus two Boston-born boys filled this honorable position.
