[EGPWS]

She did not take Schlossberg as her surname when she married.

Is she a hyphenated one?

[LibFreeOrDie]

Not hyphenated. She does not use “Schlossberg” at all in her name.

She does not hyphenate the names of her children, either. Their last name is Schlossberg, but all 3 have Kennedy as a middle name: Rose Kennedy Schlossberg, Tatiana Celia Kennedy Schlossberg, and John “Jack” Bouvier Kennedy Schlossberg.
