In the Shura ending during Sekiro's fight with The Owl, he reveals part of his name before being cut off. The only reason his full name, Ukonzaemon Usui, is known is because of lingual differences in personal name order between Western and Eastern countries that are reflected in the game's script. In the English script, the first name "Ukonzaemon" is said first, while in the Japanese script, the surname "Usui" is said first.
