I mean. Is this a new thing? I don't think my grandmothers ever got asked? But both my grandmothers were Nanny, with my dad's mom getting Nanny Mack (we are thoroughly Irish) as a distinguishing factor -- Nanny was the preferred name/title on both sides of the family. But my dad's brother's kids with his second wife called her Gramma. (My dad's brother's kid with his first wife ended up calling her Ma because my grandparents raised and eventually adopted her.) I don't think (???) there was ever a tussle over it? (Now I need to ask my aunt/cousin to find out.)
