The D in this name is pronounced like 'th'in 'brother'. )
Madra was the name of a province probably on the western front of ancient India. shalya was its ruler at the time of Mahaabhaaratham. He fought for Duryodhana, though he was maternal uncle of Paandavas.
Some people very meaninglessly associate the modern Madras to this ancient Madra region. That has neither proof nor reason except the similarity in the spelling and pronunciation.
