Will the invitation to lunch by PM Narendra Modi on April 12 bring up the old issue of the Duke of Cambridge Prince William's Indian — specifically Gujarati — ancestry that surfaced three years ago? Mitochondrial DNA that passes down from the mother's side, links Prince William to the half-Armenian, half-Indian Eliza Kewark of Surat. In 1812, she gave birth to Katharine Scott Forbes, his great-great-great-great grandmother from Princess Diana's side. That, as royalty watchers calculate, makes the future British King 1/256th Indian, perhaps even Gujarati. While the Indian population of Britain no doubt warmed to this desi tadka in their future monarch, the prince has not inherited any affinity for spice. His wife told Indian students in London this week that she likes spice but he has a hard time with it. So a traditionally mild and sweetish Gujarati farsan would be doubly appropriate for the PM's lunch.
