The same for me; at least, to the extent that i wouldn’t classify as the father of libertarianism someone who couldn’t possibly espouse contemporary libertarianism if he were living during our times. Locke would irremediably disagree with the philosophical (in particular, meta-ethical) grounds, the basic ethical views and the political consequences of libertarianism.
“The first person to describe himself as a libertarian was Joseph Déjacque, an early French anarchist communist. The word stems from the French word libertaire, and was used to evade the French ban on anarchist publications.” ~ Wiki
