86-year-old Sir Alan Williams, a veteran and decorated former officer in the British Army, lived his entire life without knowing anything about his true roots. The dramatic turning point came after his son married a Jewish woman — leading to the stunning discovery that his mother was Jewish, and had hidden her identity to protect her family. He went to Chabad House in London, closed a historic circle in tears — was called up to the Torah, put on tefillin for the first time in his life, and proudly received his Hebrew name: Avraham ben Sarah.
