Adina was born in 1928 in Mexico to her mother, Simcha Allegra née Hussani, and her father, Rabbi Mordechai Atia, one of the most famous rabbis from Aleppo. She was raised in a warm Jewish home of three brothers and six sisters. The family made aliyah in 1936 and settled in Jerusalem. Adina completed elementary school and two years of high school, then dropped out.
At age twelve, she joined Brit Hashmona’im, a youth group in keeping with the religious values of her home. The instructors in the movement left a lasting impression: Moshe Segal, Meir Medan, Baruch Duvdevani et al. Like many members of this movement, Adina enlisted in the IDF as well. One of her first roles was posting posters denouncing British rule and its troops, who killed Yair, Hy”d. Other activities she took part in were surveilling and following British officers, transporting and hiding weapons, recruiting new members for the movement, and disseminating promotional materials — both in Hebrew and in English, for the British officers.
In 1948, she enlisted in the IDF and served in the Medical Corps. After being demobilized, she started working in Hadassah and took various courses. After a course in X-ray nursing, she began working in this filed, until retiring in 1991.
In 1950, she married Yisrael Yellinek, and they had four children (three of whom live in Judea and Samaria) and numerous grandchildren. As a pensioner, Adina continued to volunteer as a teacher’s aide in schools for children with learning disabilities, helping them to learn how to read and write.
