The doctor widower of JFK's granddaughter Tatiana Schlossberg faces bringing up two young children alone after her tragic death from blood cancer aged just 35.  

George Moran was praised by his late wife in a soul-baring New Yorker essay last month revealing her terminal diagnosis and must now juggle his grief, a demanding job and caring for his three-year-old son Edwin and one-year-old daughter Josephine. 

'Our beautiful Tatiana passed away this morning. She will always be in our hearts,' a tribute from George, his children and other Kennedy family members read in an Instagram post that announced Tatiana's death on Tuesday.

Just last month, Schlossberg revealed in a candid essay for The New Yorker - published on the 62nd anniversary of her grandfather's assassination - that she had been given a year to live. 

In the piece, Schlossberg praised Moran for his support throughout her treatment, writing: 'George did everything for me that he possibly could.

'He talked to all the doctors and insurance people that I didn’t want to talk to; he slept on the floor of the hospital; he didn’t get mad when I was raging on steroids and yelled at him that I did not like Schweppes ginger ale, only Canada Dry.'

She added, 'He would go home to put our kids to bed and come back to bring me dinner. I know that not everyone can be married to a doctor, but if you can, it’s a very good idea. 

'He is perfect, and I feel so cheated and so sad that I don’t get to keep living the wonderful life I had with this kind, funny, handsome genius I managed to find.'

Tatiana Schlossberg, a 35-year-old mother of two, died on December 30, just six weeks after she revealed she was battling blood cancer

Schlossberg was the daughter of former US Ambassador Caroline Kennedy, JFK's only surviving child, and designer Edwin Schlossberg. 

She studied at Yale for her undergraduate degree, where she met her future husband, Moran, now an attending urologist at Columbia University.
