The title encompassed Count of the Holy Roman Empire, Comte de Morhange, and Graf von Port Eliot.

In 1735 Granville Elliott was set to marry Jeanne Thérèse du Han, Comtesse de Martigny and lady of honour to the Empress of Germany.

[2] Granville spent a significant amount of time in London attempting to prove that his direct ancestors, Richard Eliot and Catherine Killigrew, had married prior to the birth of their son George Elliott.

Despite his attempt failing in London, Granville was given the title Graf von Port Eliot at the Court of Lorraine.

Without an heir, Amable Gaspard Antoine Elliott chose his half brother Francis Perceval Eliot to succeed him.
