Hemkaran, also known as Pancham Singh, belonged to Benares. According to the book Chhatra Prakash, when the brothers of Pancham Singh ousted him from the throne of Benares, he visited the shrine of Vindhyvasini Devi, situated five miles west of Mirzapur and devoted himself to the most severe penance. After seven days, he decided to offer his own head to the deity. But before the consummation of sacrifice, it is said, the deity appeared and held his hand and promised him a kingdom. However, a drop of blood had oozed out of the wound that Pancham Singh had inflicted upon his neck and it was from this drop or boond that the descendants of Pancham Singh acquired the name of Bundela.
In yet another account of Orchha Gazetteer, Pancham Singh made five offerings of human heads at the shrine of Vindhyavasini Devi and then added Vindheyla to his name because the shrine was located in the Vindhyan ranges.In yet another account of Orchha Gazetteer, Pancham Singh made five offerings of human heads at the shrine of Vindhyavasini Devi and then added Vindheyla to his name because the shrine was located in the Vindhyan ranges. The Vindheyla name was later corrupted to Bundela.
Elliot gives credence to the account of the origin of the Bundelas, as given by the author of Hadiqat-ul-akalim according to which the ancestor of the Bundelas was an offspring of Bandi by a Gaharwar named Hardeo. Dr. Smith though not willing to accept this version suggests the possibility of a marriage between the daughter of the Khangar Raje of Garh Kundar and the Gaharwar adventurer who supplanted him and thinks that the Bundelas owe their origin to this union. But this does not in itself explain the origin of the word Bundela.
To sum up it seems that the name Bundela originated from the word Vindheyla which in turn was derived from the Vindhyas, the famous mountain ranges which traverse this region. It also seems highly probable that Pancham Singh was once deprived of the kingdom of his father, felt its restoration to be the boon of his deity(Vindhyavasini) and out of sheer gratitude assumed the name of Vindheyla which later contracted to Bundela. It may also be suggested that Pancham Singh might have brought under his control the region around Mirzapur where the shrine of Vidhyavasini Devi is situated and which could be the additional reason for the assumption of the name of Vindheyla.
Here it may be interesting to note that the name of one of the ancestors of Pancham Singh was Vindhyaraj which also lends credence to the probable derivation of the word Bundela from the Vindhyas.
