As a young boy, Partap Singh learnt Punjabi, Urdu and Sanskrit and studied Sikh scriptures.

During one such journey he happened to meet Max Arthur Macauliffe, then engaged in translating the Sikh scripture into English.

Partap Singh settled down in a house in Kaulsar near Baba Atal, in Amritsar, and for several years performed katha expounding the Holy Writ in front of the Akal Bung.

Volumes of the Holy Books transcribed by Giani Partap Singh are also preserved at Baba Atal and Takht Sri Hazur Sahib, Nanded.

He is also said to have translated into Punjabi Major Evans Bell's book, The Annexation of the Punjab and Maharaja Duleep Singh.

His great-grandson Harpreet Singh Giani is an advocate and a barrister currently practicing in the Punjab and Haryana High Court in India and in England and Wales.
