Rahul Gandhi on his two days visit to Jammu and Kashmir uttered these words. " When I come here(Kashmir), I feel like I am coming home".
After his statement, there were a lot of criticism that he played the kashmiri card, it was a political move, the response to his statement were varied. Now whether he played the kashmiri card or not that is a contentious matter and we all must have different opinions.
What I want to tell here are some lines from the biography of Indira Gandhi by Katherine Frank that I read last month and find interesting.

"In the opening chapter of his Autobiography, ‘Descent from Kashmir’, Nehru writes, ‘over two hundred years ago, our ancestors came down from that mountain valley to seek fame and fortune in the … plains below’. From their lofty, Edenic home in the Himalayas, Indira Gandhi’s forebears were exiled to the hot, arid plains of north-central India. The particular ancestor Nehru refers to was a Hindu Pandit rahmin elite named Raj Kaul, a Sanskrit and Persian scholar, who left Kashmir around 1716 for Delhi and became a member of the court of the Mughal Emperor Farukhsiyar who granted him a house situated on a canal in the city. Raj Kaul’s descendants came to be known as Kaul-Nehrus after nahar, which means canal, and in time this was shortened to Nehru. Raj Kaul’s great-grandson, Lakshmi Narayan, became one of the first Indian vakils, or lawyers, of the East India Company in Delhi, and his son,Ganga Dar, was a police officer in the city when the Mutiny broke out in 1857. In the upheaval of the 1857 uprising, Ganga Dar fled with his family to Agra. He died four years later and three months after his death his wife gave birth to a posthumous son who was named Motilal."
So certainly as per this genealogy provided it seems that Rahul Gandhi's statement "I can tell you that I understand you, my family must have drank water from the river Jhelum" was not baseless.
What I find more interesting is the origin of the word "Nehru".
