Son of Dean Greystock, and an MP for Bobshorough. Needing money, he played with the idea of marrying his cousin Lizzie Eustace although he was engaged to Lucy Morris."He was a good-looking, but not a strikingly handsome man; thin, of moderate height, with sharp grey eyes, a face clean shorn with the exception of a small whisker, with wiry, strong dark hair, which was already beginning to show a tinge of gray.... He was quick, ready-witted, self-reliant, and not over scrupulous in the outward things of the world. He was desirous of doing his, duty to others, but he was specially desirous that others should do their duty to him" - The Eustace Diamonds.
