Most likely at some period of history all her ancestors were brutally killed and only little remains of survived children were forcibly turkified.
For example this 80-year-old woman called Fatma Yavuz only by chance learned her real Armenian name at the age of 78. All her family were killed and she was given to a Turkish family.

Recently Fatma Yavuz sent a letter to the Turkish parliament and wrote about the suffering she endured, and demanded an apology for all this.
Here is the

Only God knows how many today's Turks living in Turkey are actually descendants of those people who were victims of invading from Central Asia tribes of genocidal killers.
