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