Given the task definition and input, reply with output. You will be given a summary of a story. You need to create a question that can be answered from the story. You can create a question about characters, events, facts and beliefs, etc. Your question should be specific, try not to use pronouns instead of full names. As the stories are sometimes movie plots, they will contain actor names in parentheses. You should not use those names. Only use character names. Try to ask a question about all parts of the plot, not just the beginning.

Valentine has fallen under the displeasure of his father by his extravagance, and is besieged by creditors. His father, Sir Sampson Legend, offers him 4000 (only enough to pay his debts) if he will sign a bond engaging to make over his right to his inheritance to his younger brother Ben. Valentine, to escape from his embarrassment, signs the bond. He is in love with Angelica, who possesses a fortune of her own, but so far she has not yielded to his suit. Sir Sampson has arranged a match between Ben, who is at sea, and Miss Prue, an awkward country girl, the daughter of Foresight, a superstitious old fool who claims to be an astrologer. Valentine, realizing the ruin entailed by the signature of the bond, tries to move his father by submission, and fails; then pretends to be mad and unable to sign the final deed of conveyance to his brother. Finally Angelica intervenes. She induces Sir Sampson to propose marriage to her, pretends to accept, and gets possession of Valentine's bond. When Valentine, in despair at finding that Angelica is about to marry his father, declares himself ready to sign the conveyance, she reveals the plot, tears up the bond, and declares her love for Valentine.
What is the name of Valentine's father?
