This may be Rémy Granville Mignot (1861-1927), the son of the South Carolina-born landscape painter, Louis-Rémy Mignot (1831-1870), a friend of the Whistlers. He married Zairah C. Harris of Baltimore and their son, Rémy Granville Mignot, was born in Baltimore. Louis-Rémy Mignot died prematurely in Brighton leaving his widow and son in poverty; his widow organised a memorial exhibition in Paris in 1876.
By 1868 the family was in England and Rémy remembered his father taking him with Whistler, William McNeill Whistler (1836-1900) and Algernon Charles Swinburne (1837-1909) to see 'Blue-Gown' win the Derby. 1
Rémy Granville Mignot married Hilda C. Bradley (1897-1950) and they had two children, Marjorie Cordelia (1897-1950) and Brian Boyse (1902-1967) before being divorced in 1906. With his second wife, Edith Constance Mignot, he had another son, Adrian St Rémy Mignot (1909-1975). Like his father, Rémy Granville Mignot was an artist, but was not very successful; he died in Stepney, England. 2

The figure is lightly outlined and roughly shaded, the lines being soft and rather uncertain. There is a tiny area of white highlighting the boy's head.
It was not, as far as is known, exhibited in Whistler's lifetime.
