Have we just lost the last person who was alive in the 19th century?

Misao Okawa, born March 5, 1898, has died. She had the distinction of being the oldest person alive, but who is the oldest person now?

Japan identifies a 115-year-old woman as its new oldest person. She was born on March 15, 1900. Perhaps beyond Japan, there is someone older, but it may be that there is suddenly no one left from the 19th century.

IN THE COMMENTS: I am made to regret that I didn't title this post: Have we just lost the last person who was alive in the 1800s?
