My blessed GK call me Nanna. I wanted to be called Nanna_____ by my son's 2 adopted daughters 'cause SIL mom was Nanna too. But Nanna stuck. My hubby passed when daughter only had 3 & he was called PawPaw. That's what I called my paternal granddad & paternal grandma was MamMaw. My maternal grandma was called Nannie. My is still living & she's called Grandma. My dad passed 10 yrs ago & he was called Grandpa.
