How far is it true that Priyanka Vadra has changed her son’s name from Rehan Robert Vadra to Rehan Rajiv Gandhi? If true, why?

Authenticity cannot be claimed
But if true then the only reason being after Rahul there is no male so called Gandhi and the legacy of the family has to contnued
First of all the Surname Gandhi was got imposed on Mr. Firoz by none other Mr. Gandhi he was very bitter of Nehru's policies and was dumped by the Family same happened to Maneka Gandhi and Varun Gandhi
Deliberately and will fully all the institutions of India have been named after members of the Family
The family has given three PM and all of them have been conferred with Bharat Ratna
The only two non Family PM that congress has given are Late PV Narsimha Rao and Manmohanji both have in their tenure done a lot for the country credit for which is being taken by the Family
Even Manmohanji has been dumped its the policies which are being compared With the current PM yet he has not been projected as future PM if the party comes to power
So in continuation to this policy of the Family the next crown prince would be Rehan Rajeev Gandhi may be this might be the reason
