What is my half-sister's granddaughter to me?
Your half-sister's granddaughter is your half-great-niece. Your half-sister shares one parent with you, and their granddaughter sits two generations further down the same line. From the other side, you are their half-great-aunt or half-great-uncle — each further generation down adds another 'great' to both titles.
