1. "panchayat register (village register)" does not confer any Title-Ownership Rights over the immovable property. The office of the Panchayat, maintains records ONLY for the purpose of Services /Tax /Cess /Levy of the local body, applicable to the immovable constructed property within its jurisdiction.
2. In the absence of a registered Will document of the deceased parents, the legal solution, for a Clear Marketable Title, would be to get a Stamp Duty paid Registered "Family Settlement Deed" for the immovable land property, with mutual consent of all the residual legal heirs, before the Registrar of Sub-Assurances.
3. Using the services of a local lawyer and documents like Ration Card or Aadhar Card or Birth Certificates, etc...., for conclusively proving the legal heir''ship /blood relation with the deceased parents, of all the legal heir/s, the above point no. 2, can be successfully concluded, to include the name of the participating & Consenting Legal Heirs, in the Revenue Office Records
