The Aryans regarded Aryan life as being more precious than non-Aryan life, and would not risk losing it in battle. So the troops that were assembled to fight the armies of Mahmud of Ghazni were all taken from non-Aryan populations, and made honorary members of the Kshattriya, or warrior caste, and allowed to wear their battle-dress and emblems. They were taken from many different ethnic groups who spoke many different languages and dialects. Some were Lohars and Gujjars, some were Tandas, some were Rajputs, non-Indian peoples who had come to live in India some centuries before, and some may also have been Siddhis, Africans from the East African coast who fought as mercenaries for both the Hindus and the Muslims. This composite army moved out of India through the mountain passes and west into Persia, battling with Muslim forces all along the eastern limit of Islam. While this is to an extent speculative, it is based upon sound linguistic and historical evidence, and provides the best-supported scenario to date. Because Islam was not only making inroads into India to the east, but was also being spread westwards into Europe, this conflict carried the Indian troops - the early Roma - further and further in that direction, until they eventually crossed over into south-eastern Europe about the year 1300. 
Konkani is our Mother Tongue. It is an Indo Aryan language that has its roots in Sanskrit. There are several dialects. Although originally Konkani was the language of Saraswat Brahmins who settled in Goa, millions have adopted it as their mother-tongue. It is now spoken by 4.5 million people in all religions - Hindu/Christian/Muslim. Konkan denotes a place. The coastal Maharashtra to the north of Goa, consisting of Ratnagiri, Malwan etc. In the Puranas and other ancient writings there is a mention of 'Sapta Konkana' or seven Konkans. These seven Konkans were in the west coast of India.Although Konkani language is identified with an area geographically, it is surprising that only , the Gowda Saraswat Brahmins are called 'konkanis'. Although many others have Konkani as their mother-tongue, they are not called 'konkanis'
