"Giovanni Carlo Doria (1576-1625) (also Gio, Gian, or Giovan) was a Genoese art collector and mecenas of the early 17th century. A son of Agostino Doria, doge of Genoa in 1601-1603, he was a prominent member of one of the richest and most influential families of the Republic of Genoa; his brother Giovanni Stefano Doria (1578-1641) became the 101st doge of Genoa (1633-1635) and was considered the richest man in Italy in his day. Giovanni Carlo was married to Veronica Spinola, daughter of Ambrogio Spinola. He was given the Order of Santiago by Philip III of Spain.
His collection of 463 paintings was partly legated to this elder brother Marcantonio Doria (born 1572) after the death of Giovanni, and elements of it would stay in the possession of the family for centuries. Three inventories of the collection are known, one from 1617, a revised one from ca. 1621, and one from after his death in 1625." - (Wikipedia (en) 09.12.2020)
