Akira Sulu (20th century)

Sulu was a young human who lived during the 20th and 21st centuries. He was a distant ancestor of Starfleet officer Hikaru Sulu.

When Hikaru Sulu traveled back in time from 2286 to 1986, Hikaru and his distant ancestor happened to meet each other on the streets of San Francisco. The child believed Hikaru Sulu to be his uncle, and Hikaru was similar in appearance and shared a name with this uncle. Hikaru recognized the child almost immediately, having seen pictures of his ancestor at various stages in his life. After the meeting was finished, Doctor Leonard McCoy asked Sulu who the child was, and Sulu informed him that the child was his distant ancestor. (TOS novelization of Star Trek IV: The Voyage Home).
