Porus
The King Porus of Alexander's time seem to reflect the old tribal name. Kosambi mentioned that the Puru name perhaps survived in the modern Punjabi surname Puri, while Naval Viyogi (1966) mentions in his work on the IVC that the modern Punjabi surname Puri may possibly originate with the Puru tribe. Buddha Prakash (1964) mentions that the Puru clan probably survived in Punjab under the name of Puri.
