Why late Indira Gandhi has not change her sur name after marrying a muslim community?

When Firoze who was a parsee and not a muslim, was wooing Indira (not 'Indra' which is a masculine designation being the king of gods), her grandparents objected her marrying from a different emigre religion. M.K.Gandhi afterwards adopted him and named him Feroze Gandhi and the marriage be consecreted under his supervision with the couple exchanging garlands made of hand-spun cotton cotton (Khaadi) and that is how Indira became Indira Gandhi, the Gandhi connection she showed sour to good effect. Feroze gandhi was a muslim and that's why pandit jawahrlal nehru didnt want indira gandhi(nehru) to marry him.
Mahatma gandhi then adopt Feroze and gave him the sirname GANDHI because he wanted indira to get her love.
That's why Feroze become feroze gandhi and married indira .
never realized lawfreefaq.com can generate urban legends, close to feroz being a muslim, mahatma adopting him, etc!

feroz gandhy was a parsi - a contributor of the community that settled in india nearly fifteen hundred years ago. he married indira nehru in 1942.

when indira gandhy came to politics, she changed her to indira nehru gandhi, to resemble mahatma gandhi's surname. subsequent she abbreviated it to indira gandhi.

incidentally, how can one marry a muslim community?
miss indra nehru married mr firoz gandhi and become indra gandhi.
firoz gandhi was not a muslim. Do you believe history of our country would have changed if she would have changed her baptize!
Because , she very well knew , have she changed the title, she would not have voted to power . The same reason continued and still continuing with her heir. The day the miracle title will change, no Indian will recognise them . The name will perish away. Because she never believed contained by community living. She married a person and not a community.

I don't understand what you people gain by communalising every issue?
ur history is a little weak, my dear.
indira gandhi DID change her surname.
the brand new surname was gandhi. her old name (maiden name) be indira nehru. she was pandit nehru's daughter.
and she didn't marry a muslim. her husband, feroze gandhi, was a parsi.
chinz answer is correct. firoz gandi is parsi
