His father?

His father was an Ahmadi named Seth Abdullah Allahdin (or spelled Alladin). Abdullah Alladin wrote “The Claims and Teachings of Ahmad, the Promised Messiah and Mahdi” published as a second edition in 1917, from Secunderabad, India, which is central India. This proves that Ahmadiyya had spread to deep South Central India by 1917. The title of this book also lists how there is an Ahmadiyya Jamaat book depot in Ceylon (slave island), which is modern day Sri Lanka. His father devoted a large part of his wealth to the Mirza family (see page 53), he seems to have converted to Ahmadiyya in the 1910’s. In 1922, he wrote a translation of the Quran in english, a sort of translation with hadith, however, he only picked certain verses of the Quran.  His PDF version of the same book, republished in 1918 can be downloaded here. The Imam Of the Age by Seth Abdullah Allah Din (1918). In this book, he even quotes MGA’s letter of Takfir to Dr. Abdul Hakim Khan. A 1916 version of the same book can be found here: Claims and Teachings of Ahmad (1916).

His father was mentioned in the ROR of 1919

“”””Among honorary workers, the name of Seith Abdullah Allah Din of Sikandrabad deserves special mention. He is filled with great zeal for the propagation of the truth taught by the Ahmadiyya Community and has spent thousands of rupees in publishing and distributing Ahmadiyya literature. He has only recently succeeded in winning over a learned Imam of Sikandrabad whom he now wishes to employ as an Ahmadi preacher and has asked him to prepare himself for that purpose. It is gratifying to learn that many a seeker after truth has benefited by the literature published by our brother and Ahmadi preachers are making the best use of his publications. They are mostly English and Gujrati translations of the writings of the Promised Messiah.”””
