The purans are ancient History. While we accord recognition and respect Western History, we do not have the same attitude to Indian Puran. So much for our English Education. We would believe as authentic Homer's Iliad and Odyssey, think of Hercules as having existed but when we recover the skeletons purported to be that of Kadothgaja, we say it is non sense. This despite the detailed descriptions of cities, people, Dynasties and Geographical descriptions which exist even to-day. I have posted details of the Manu Dynasty. Here is the Dynasty of Lord Krishna. And this includes Lord Krishna's sons, Grandsons.
