grandniece

The chest A. was not to be opened until the eldest son of his grandniece, Lady Laura, should attain the age of twenty-five.

Mother said you were up on the Bay then at your grandniece's—pretty girl.

She was a grandniece of the great Jean Jacques Rousseau, and flourished in the first part of last century.

She is a grandniece of mine; her father died some years ago, her mother three years since, and naturally she came to me.
