ok- my side of this....
my dad's side...no history as all passed on very early...
my mom's side....Grandma, the only grandparent I met, although I met my dad's grandfather, but did not have a name for him.

DH's side... Granddaddy and Grammie seemed to work for both sides

Our DD said Grandma and Poppy for my parents, and Grammie and 'More Daddy" for Bill's parents- a funny story I need to scrap.

Our older grandson calls up Granddad and Grandma

now for the munchkin, who turned one on Saturday...we are just 'noise', LOL sometimes... I am "ah Gee Gee" with up stretched arms. Hoping the child speaks English one day.
