 Given Benares's close ties to Nepal, it was not surprising when Sir Prabhu Narayan married a daughter of Jang Bahadur Kunwar Ranaji, the Prime Minister of Nepal and Maharaja of Kaski and Lamjung, as his first wife.He later married a distant relation of the family, a sister of Babu Jagdep Narayan Singh.Dying in 1931, aged 75, Maharaja Sir Prabhu Narayan was succeeded by his only son, Captain Sir Aditya Narayan Singh.
