Eva Gabor's youngest sister

Isn't it a small world that we live in
It may seem so huge at times 
But sometimes it seems so insular
So teeny weenie; everything meets!
My cousin was engaged to
Eva Gabor's youngest sister Kati!
Or was it maybe: her cousin?
Her youngest sister's daughter? 
I was just a little kid so maybe
I got it wrong: I don't really know but
She was beautiful, she was cute
She said her sister was famous
I thought my cousin loved her
They looked good together
That was all that mattered to me
That's how I saw it as a little kid!
