Ramdas Gandhi (1897-1969), Devdas Gandhi (1900-1957)

Ramdas Gandhi (1897–1969) was the third son of Mohandas Karamchand Gandhi. He was born in South Africa. He outlived his parents and all of his brothers. He and his wife Nirmal had three children; Sumitra Gandhi, Kanu Gandhi and Usha Gandhi. He was active in his father's Indian independence movement.

He had no taste for asceticism, yet participated in the grueling civil protests of the 1930s. Numerous jailings had serious effects on his health. Born and raised in South Africa, he never adjusted to the idealistic poverty imposed by his father. He had a taste for hunting. He died in the year of his father's centenary. At his father's funeral, Ramdas Gandhi was the one who lit the fire to start the cremation, as Mahatma had wished for. He was joined by his younger brother Devdas Gandhi at the funeral.

Devdas Gandhi (1900–1957) was the fourth and youngest son of Mohandas Karamchand Gandhi. He was born in South Africa on the 2.October and returned to India with his parents as a young man. He became active in his father's movement, spending many terms in jail. He spent a lot of time with his father. He also became a prominent journalist, serving as editor of Hindustan Times.

Devdas fell in love with Lakshmi, the daughter of Rajaji, Devdas's father's associate in the Indian independence struggle. Due to Lakshmi's age at that time – she was only fifteen, whereas Devdas was twenty eight years – both Devdas's father and Rajaji asked the couple to wait for five years without seeing each other. After five years had passed, they were married with their fathers' permissions in 1933. Devdas and Lakshmi had four children, Rajmohan Gandhi, Gopalkrishna Gandhi, Ramchandra Gandhi and Tara (Bhattacharya)

Alone of all the sons, Devadas stayed near his father, sometimes being granted the privilege of serving as his secretary.  

Mohandas acted as midwife at the delivery of his youngest son, Devadas Gandhi (1900-1957)..
