He married his first wife Meharqanda in 1912; she was a daughter of Yar Mohammad Khan of the Kinankhel clan of the Mohammadzai tribe of Razzar, a village adjacent to Utmanzai. They had a son in 1913, Abdul Ghani Khan, who would become a noted Artist and poet. Subsequently, they had another son, Abdul Wali Khan (17 January 1917–), and daughter, Sardaro. Meharqanda died during the 1918 influenza epidemic. In 1920, Bacha Khan remarried; his new wife, Nambata, was a cousin of his first wife and the daughter of Sultan Mohammad Khan of Razzar. She bore him a daughter, Mehar Taj (25 May 1921 – 29 April 2012), and a son, Abdul Ali Khan (20 August 1922 – 19 February 1997). Tragically, in 1926 Nambata died early as well from a fall down the stairs of the apartment they were staying at in Jerusalem.
