It's important to note that:
* Surnames are not always indicative of a specific community or caste. They can vary widely within communities and even across regions.
* Many Marathi Brahmin surnames exist. Some common ones include Deshmukh, Joshi, Kulkarni, Patwardhan, Apte, etc.
If you are researching a specific individual with the surname Surange, it would be more helpful to focus on their specific lineage and family history rather than relying solely on the surname.
