Mary was born around 1914, sandwiched between her Soma-born older brothers (Takis, John Lazare) and her Smyrna-born younger brother Constantine. Whether she was born in Soma or Smyrna is one of the open dating questions.
She arrived in New York on the SS Normandie in 1938 — the manifest entry being the strongest fix we currently have on her age and pre-emigration location. The trail after the arrival is still cold.
