John-Henry Hill was born in the U.S.A. in 1791. In 1821 he marries Fanny-Francis-Maria Mulligan, and together they come in Athens. In July 1831, Greece's first girls' school (Parthenagogeion) is founded in Plaka, near the Archaia Agora. In the beginning there were a few schoolgirls, but after a few years they reached the number of 500.
