Edward Camille is my grandfather. Better known to my family as Daddy Ed. 
My grandmother, Mary Viivian is better known to my family as "Muh". 
I was the first grandchild and my mom and her sisters called them 
Mother and Daddy (naturally). I couldn't talk very well and they got
 stuck with new names. It wasn't long before everyone was calling them 
Muh and Daddy Ed.
