Hugh Auchincloss 3d | Kennedy relative, 87

Hugh D. Auchincloss 3d, 87, stepbrother and lifelong friend of Jacqueline Kennedy Onassis, died Saturday of B-cell lymphoma at his home at Hammersmith Farm in Rhode Island, according to his children.

Mr. Auchincloss, who was known by the nickname "Yusha," was also a stepsibling to the writer Gore Vidal.

Jackie Kennedy and Mr. Auchincloss were teenagers - he was a year older - when her mother, Janet Lee Bouvier, married his father, Hugh D. Jr. The two were close before the marriage and remained close until Onassis died in 1994, according to his daughter, Maya.

"They had a lot of respect for each other and whoever the other one was seeing, they would introduce and meet and get each other's approval and advice about things," she said.

After living in Washington and New York, Mr. Auchincloss spent the last few decades of his life in Newport, R.I., where he was involved in causes including the environment, the historical society, and the U.S. Naval War College. He had a lifelong interest in the Middle East. - AP
