Ethel Kennedy has passed away at the age of 96. 

Robert F. Kennedy's widow and the Kennedy family matriarch suffered a stroke in her sleep last week and died in a Massachusetts hospital Thursday, surrounded by family. 

White roses were delivered to the John F. Kennedy Hyannis Museum on Thursday afternoon.  The museum's executive director Wendy Northcross tells the Cape Cod Times that white roses were Ethel's favorite, and they are on display in the lobby along with a condolences book.
