In page Shoghi Effendi:

"

Throughout Shoghi Effendi's life, nearly all remaining family members and descendants of ʻAbdu'l-Bahá were expelled by him as covenant-breakers when they didn't abide by Shoghi Effendi's request to cut contact with covenant-breakers, as specified by ʻAbdu'l-Bahá.[3] Other branches of Baháʼu'lláh's family had already been declared Covenant-breakers in ʻAbdu'l-Bahá's Will and Testament. At the time of his death, there were no living descendants of Baháʼu'lláh that remained loyal to him.[4]
