Princess Gesine Doria Pamphilj has an estimated net worth of $750 million. The Pamphiljs, Prince Jonathan, 47, and Princess Gesine, 46, were adopted by Frank Pogson, a British naval frigate commander from Kent, who died in 1998, and his wife, the London-born Princess Orietta Doria Pamphilj, who died in 2000. The couple met when Pogson was stationed in Ancona in the latter part of the second world war and married in 1958. Two babies called Archibald and Mary were whisked from a Catholic orphanage in London in the 1960s by the couple, who could not have children of their own, renamed and brought up in the family’s Rome palace. Jonathan and his sister Gesine inherited the family fortune, including the Palazzo Doria Pamphilj in Rome and one of the greatest private art collections in the world, including works by Caravaggio, Titian, Raphael and Rubens. The siblings were locked in a battle over whether two children born to Jonathan by surrogate mothers have any legal rights to the family fortune. The children are being raised by him and his Brazilian boyfriend. Gesine, who is married and has four daughters, has decided not to appeal against a Rome judge’s refusal to hear the case. The estate has been valued at anything from £950m to well over £1 billion, but as the art collection cannot be broken up and with any tax implications in a sell-off, Sunday Times Rich List valued the Pamphiljs at £500m.
