What is a half-niece?
A half-niece is the daughter of your half-sibling — the child of a brother or sister who shares one parent with you. She stands one generation below you, just like a full niece; the 'half' simply records the single shared parent at the top of the line. From her side, you are her half-aunt or half-uncle.
