My parents are Lao Lao (Mandarin for maternal grandmother) and Papa to our kids. My mother-in-law is Grandmama, and my late father-in-law was Granddaddy.

My maternal grandparents, who are still living, are Nanny and Paw (not sure how that spelling evolved from Pa, but it did). My paternal grandparents were Mamaw and Papaw.
