Source-derived summary

Athina Mary "Tina" Onassis Niarchos (née Livanos; Greek: Αθηνά "Τίνα" Λιβανού, pronounced [aθiˈna ˈtina livaˈnu]; 19 March 1929 – 10 October 1974) was an English-born Greek-French socialite and shipping heiress. She was second daughter of the Greek shipping magnate Stavros G. Livanos and Arietta Zafirakis. Niarchos was also the first wife of Aristotle Onassis, and later married her older sister Eugenia's widower and Greek shipping tycoon, Stavros Niarchos, who was her first husband Onassis's arch-rival. She was also an elder sister of George Stavros Livanos.

Marriages and family

She was married three times. Her husbands were:

Aristotle Onassis (28 December 1946 – 1960); with him she had two children, Alexander Onassis (1948–1973) and Christina Onassis (1950–1988). She divorced him upon discovering that he was having an affair with the opera singer Maria Callas.

John Spencer-Churchill, Marquess of Blandford (23 October 1961 – March 1971), later 11th Duke of Marlborough.

Stavros Niarchos (21 October 1971 – 1974), her sister Eugenia's widower.

After her divorce from Aristotle Onassis, she resumed using her maiden name, Livanos, until her marriage to Spencer-Churchill.

Editorial analysis

Why this record matters

The phrase “english-born Greek-French socialite and shipping heiress” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Evidence profile

Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 17, 2026. The linked authority identifier is Q3564608. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1929, 1974, 1946 and 1960.

Critical limits

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it
