What is a great-nephew?
A great-nephew is the grandson of your sibling — your niece's or nephew's son. He sits two generations below you on your sibling's line. Genealogists sometimes write 'grand-nephew', which means exactly the same thing. From his side of the family tree, you are his great-aunt or great-uncle.
