Doria-Pamphili-Landi (or Doria-Pamphilj-Landi) is a princely Roman family of Genoese extraction. Legend has that the origins of the Doria family date from the early 11th century, but the authentic pedigree is traced to Ansaldo d’Oria, consul of Genoa in the 12th century. The descent of the several Doria lines in Genoa is well-known and appears described in Natale Battilana’s 19th century genealogical study of old Genoese families.
The Doria-Pamphili-Landi princely family is a subbranch of the Doria di Oneglia branch: in 1291 two Doria brothers bought the lordship of Oneglia, which was co-owned by their descendants until the late 15th century. Admiral Andrea Doria was descended from a Doria di Oneglia, Genoese soldier Aitone Doria (also called Antonio Doria) who fought for the French at the battle of Crécy.
One of the most famous members of the family was Andrea Doria, perpetual censor of Genoa in 1528 and admiral to the emperor Charles V, who was created Prince of Melfi (1531) and marquis of Tursi (in the kingdom of Naples) in 1555. These titles were inherited by Gian Andrea Doria, son of Giannettino Doria who was a second cousin and adopted son of Andrea Doria. Giannettino Doria was killed in 1547 during the Fieschi conspiracy against the power of Andrea Doria over Genoa and his descendants inherited the titles granted to the great Admiral. Another famous member of the family was Cardinal Giovanni Battista Pamphilj, who rose to the Papacy as Pope Innocent X.
