Girolamo II Angelo Flavio Comneno (Latin: Hieronymus Angelus Flavius Comnenus;[1] 1629–1687) was the Grand Master of the Constantinian Order of Saint George from 1679 to 1687.
[3] In the mid-15th century, Andrea's uncles Andrea and Paolo were officially acknowledged as descendants of the Angelos emperors by Pope Paul III (r. 1534–1549) and founded the Sacred Military Constantinian Order of Saint George,[4][5] a chivalric order with invented Byzantine connections.
[6] Girolamo's father Andrea, and then Girolamo himself, had challenged the claim of Angelo Maria Angeli (grand master 1634–1678) to the grand mastership of the Constantinian Order,[7] on the basis of Angelo Maria's father Michele Angeli having been born illegitimate.
[7] Girolamo maintained the friendly relationship that had been established between Angelo Maria and Leopold I, Holy Roman Emperor.
He was succeeded as grand master by his younger brother, Giovanni Andrea II, the last male member of his family.
