The de Gaulle family produced several 20th-century officers, Resistance members, and French politicians. There is a widespread notion claiming that the particle in "de Gaulle" is derived from a dialectal form of the article (it should logically be written De Gaulle, for one writes Le Châtelier, but usage has always favoured the lowercase form). However, the genealogy of this ancient bourgeois family, established by the general's grandfather, Julien Philippe de Gaulle, alumnus of the École Nationale des Chartes, shows that his ancestors, capitaines-châtelains of Cuisery, Saône-et-Loire in the 17th century, have always written their name in this way. Note: This family tree is not intended to be exhaustive, but rather aims to show the principal public figures of Charles de Gaulle's family.
