6. Semyon and Yasya were mentioned in a 1979 NYT article:

Buying watermelon on a recent evening, 25‐year‐old Semyon Shtayner and his wife, Yasya — and 2‐year‐old Felix, bright‐eyed in a stroller — were part of a Red Apple crowd that was plainly reveling in the array of fruits and melons. “In Russia, harder to get,” Mr. Shtayner explained. Like many of his countrymen here, he drives a taxi (as he did back in Chernovetse), earning $700 a month. He pays â300 for a one‐bedroom apartment. With a wide grin, he said that he had “enough food, enough clothes, enough job,” as he also did in the Ukraine; that he goes to synagogue “not every week” and that he really left to get “a good life, a Jewish life, a free life.”
