by the law of the Kingdom of Ireland, he would be the next heir to the Earldom, if restored. Since he died before Hugo Eugenio, he does not appear to have called himself Earl, but Owen Roe O'Neill, Earl Hugh's half-nephew and a general in the War of the Three Kingdoms, acknowledged "that all the immediate right to the earldom of Tyrone belongs to Don Constantino, who is in Spain" and that while he lived, Owen Roe himself "could claim nothing". By 1660, therefore, the Earldom of Tyrone was forfeit by English standards. Nonetheless, by Spanish and Irish standards the collateral O'Neill descendants of Mathew "Ferdocha" O'Neill, were allowed to use the title in Spain until 1692. At that point, it went to the senior member of the descendants of Prince Shane O'Neill, the half brother of Mathew "Ferdocha" O'Neill. Hugh Dubh O'Neill, (c. 1610c. 1666), nephew of Owen Roe O'Neill (by his brother Art Oge) and so grandnephew of Earl Hugh, and commander under his uncle in Ireland, where he held Limerick against Henry Ireton during a long siege.

Born in Armagh, served as a captain in Flanders starting in 1636. Fought in the War of the Confederacy, returned to Flanders and was given permission to raise and Irish regiment in 1663. In 1673, "became Earl of Tyrone after the death of Hugo, son of Henry mac Eoghain Rua". Died 1681 in Barcelona.
