By the time Morgan died, he owned three plantations and large numbers of African slaves. He left most of his estate to his wife for the rest of her life. On her death, most of his land and slaves passed to his nephew Charles, second son of Robert Byndloss, who served as Chief Justice of Jamaica in 1681. Morgan also left a parcel of land in the now-defunct parish of St George to another Robert Byndloss (born c. 1673) the eldest son of his brother-in-law Robert Byndloss.
