Gujrati & Marwari community is spread all across india. But what they did, they adpoted local culture/local language. They might be talking within themselve with their mothertongue, but within society, they always talk in local language. Even in chennai too, they are. But local tamilians never opposed them. I am pretty sure, even in small towns from maharshtra, you will find them. Such a perfect blending with local culture. Thats why, there are most successfull communities among India.
