In 1945, her eldest sister Jeanne Lourdes Murray (1919–2013) married the American billionaire Alfred Gwynne Vanderbilt Jr.
In 1961, her other elder sister Patricia Roche Murray (1920–2018) married the American tennis champion Sidney Wood[2] and one year after his death, in 2010, the former U.S.
[2] Catherine di Montezemolo and her husband became fixtures in the Southampton, where she spent her summers as a child on a vast beachfront property along Wickapogue Road that came to be known as the "Murray Compound" because so many family members built houses near one another.
