Like his older brother Beverley, at 14 years of age, Madison was apprenticed to his uncle, Sally's brother John Hemings, the most skilled artisan at Monticello, to learn carpentry and fine woodworking; his younger brother Eston joined him two years later. This gave each of them a valuable trade. All three of the Hemings brothers also studied and learned to play the violin, the instrument associated with Jefferson. Beverley, the oldest, was good enough to be invited to play at dances held by the Jeffersons at Monticello. As an adult, Eston Hemings made a living as a musician and entertainer in Ohio.
