John Stewart (Robert Ross)

Robert was one of the brothers of Harriet Tubman. For 11 years Tubman returned again and again to the Eastern Shore of Maryland, rescuing some 70 slaves in 13 expeditions, including her three other brothers, Henry, Ben, and Robert, their wives and some of their children.

Robert Ross (John Stewart) married Mary Manokey, who was enslaved by Dr. Anthony Thompson. Harriet Tubman was never able to rescue Mary Manokey and her children, John Jr., Moses, and Harriet. They remained enslaved on the Eastern Shore until Maryland abolished slavery in 1864. John Jr. and Moses eventually moved to Auburn, NY to be with their father, John Stewart.  (1)
