When Late Indira Gandhi fell in love with Feroz Khan while studying in abroad and cross the limit before marriage, Late Mahatma Gandhi immediately adopted to Feroz Khan and given his name as Feroz Gandhi, then after he became Feroz Gandhi. Then Gandhi family continued as Indira Gandhi, Rajiv Gandhi, Sanjay Gandhi, Soniya Gandhi etc., But in a democratic country it is permissible to change the name as per prevailing law. All the Indian politicians change their stand as per the need & situation and say intention was not like that etc. One time they admit and one time they deny. It is a political game.(Ismailsk)
