The Eleventh group was established in 1952 by Chief/ Jack  El-Eissa  and it was called the Immaculate Conception( الحبل بلا دنس)Group.

 And its headquarters was in the collége de Frére School in Toman Bay Street, then it moved to the Don Bosco Salesian Church in Salim I Street, then the group’s headquarters settled in the Church of the Holy Family to this day.

 The new headquarters was not suitable due to its narrow size and lack of capabilities, but the group did not stop its activities and resisted despite the circumstances and became stronger than it was, and the group set the strongest example in the strength of its leaders and their intelligence to overcome difficulties by holding meetings outside the headquarters and in different places.
