Francesco II Gattilusio was the second Gattilusio lord of Lesbos, from 1384 to his death. He was the third son of Francesco I Gattilusio and Maria Palaiologina, the sister of the Byzantine emperor John V Palaiologos.

John VII Palaiologos or Palaeologus was Byzantine emperor for five months in 1390, from 14 April to 17 September. A handful of sources suggest that John VII sometimes used the name Andronikos (Ἀνδρόνικος), possibly to honour the memory of his father, Andronikos IV Palaiologos, though he reigned under his birth name.
