What is the first name of Lord Grantham?

The first name of Lord Grantham is Robert.

Lord Grantham is Robert Crawley, the fictional seventh Earl of Grantham in Downton Abbey. He lives at Downton Abbey with his wife, Cora, and their daughters Mary, Edith, and Sybil. In formal contexts he is addressed by his title, but Robert is his given name and the name used by family members and close associates.

Robert inherited responsibility for the estate and treats himself less as its owner than as its caretaker. His marriage to Cora, an American heiress born Cora Levinson, helped resolve the financial difficulties left by his father and preserved Downton’s future. Their relationship also connects the old British aristocracy with the wealth of America’s Gilded Age.

Robert is played by Hugh Bonneville. A common confusion is to identify “Lord Grantham” with the actor rather than the character: Bonneville is the performer, while Robert Crawley is the character. The title itself is fictional in the series, even though an historical Earl of Grantham existed in the English peerage from 1698 to 1754.
