'role' as in an actress taking on the role of playing the wife of Winston Churchill in a movie

Kristin Scott Thomas was willing to take on the role of wife

Clementine Ogilvy taking on the role of wife to Winston Churchill in real life

Clementine Ogilvy was willing to take on the role of wife

With English you must decide from the context which meaning is meant and I think in the context of Rawat's life it was Clemetine and not Kristen but I am just as confident that your take is correct and not mine
