What to call grandparents?

Hi! Husband's dad and my dad are both from the Hokkien dialect group. What should my baby call his paternal grandfather (my husband's father) and maternal grandfather (my father)??? Is one Ye Ye and the other Gong Gong? Or Wai Gong? My husband never met his grandfather so he doesn't know. I used to call my paternal grandfather (my father's father) Gong Gong. But my husband's father is saying my baby should address him as Ye Ye, and not Gong Gong. Very confused!
