It is funny claim that Marathi never migrated. In Indore, Gwalir, and other Malva regions in MP and kanpur and jhansi area of UP; in Rajasthan and Gurjrat many marathi families came and settled. The Scindhias in MP, the Queen of Jhansi in UP, Tatya tope of Bithur UP, Holkar of Indore Mp and Gayakwad of Gujrat all are Marathi. The CM of Rajasthan is a Marathi. A kings could never gsettle alone in an area, they always follwed by big army and lots of people. If all these kings settled in a particular area of MP and UP, they did not migrate alone. You can see marathi culture in vilages of Janshi, Bithur in Up easily.
