[5][6] Feroze was the youngest of the five children with two brothers Dorab and Faridun Jehangir,[7][8] and two sisters, Tehmina Kershasp and Aloo Dastur.

The family had migrated to Bombay from Bharuch (now in South Gujarat) where their ancestral home, which belonged to his grandfather, still exists in Kotpariwad.

[9] In the early 1920s, after the death of his father, Feroze and his mother moved to Allahabad to live with his unmarried maternal aunt, Shirin Commissariat, a surgeon at the city's Lady Dufferin Hospital.

Feroze attended the Vidya Mandir High School, and then the British-staffed Ewing Christian College, Prayagraj.

Then he became closely involved with the Nehru family, spending significant time at Anand Bhawan, their residence and a key hub for political activity.

Feroze met Kamala Nehru and Indira among the women demonstrators picketing outside Ewing Christian College.

He was imprisoned in 1930, along with Lal Bahadur Shastri (the 2nd Prime Minister of India), head of Allahabad District Congress Committee, and lodged in Faizabad Jail for nineteen months over his participation in the independence movement.

Soon after his release, he was involved with the agrarian no-rent campaign in the United Province (now Uttar Pradesh) and was imprisoned twice, in 1932 and 1933, while working closely with Nehru.

After being a member of the provincial parliament (1950–1952), Feroze won independent India's first general elections in 1952, from Rae Bareli constituency in Uttar Pradesh.

Indira, who stayed with her father at Teen Murti House, the official residence of the prime minister, was at that time away on a state visit to Bhutan.
