Francis Bradley Bradley-Birt, Twelve Men of Bengal in the Nineteenth Century (1910)
“ The Kapur family was one of considerable antiquity and great distinction. The founder of the Burdwan branch was Abu Rai of Kotli in Lahore, by caste a Kapur Kshatriya, who settled in Bengal in the middle of the 17th century, being appointed 'Choudhuri and Kotowal of Rekabi Bazaar' under the Fauzdar of Chakla Burdwan. To the estate that he founded his descendants gradually added further possessions, generation after generation playing its part in building up the immense property which Mahtab Rai was finally to complete and consolidate in the nineteenth century. ”
