On April 24, 1794, Birkbeck married Prudence Bush, daughter of Richard and Prudence Bush of Wandsworth, Surrey. After 20 (math error) years of marriage, Prudence died on October 25, 1804, leaving her husband with seven children. In 1814, accompanied by his friend George Flower, Birkbeck traveled in recently defeated France. His Notes on a Journey through France (1814) revealed a good-tempered, fair-minded observer, well grounded in science and the humanities.
