Very curious to know about another name for grandma that as a family we have always used. I'm 62 and my grandma , and great grandma were known by the grandchildren as mamam. Even my nieces children call my mum mamam. I'm a nottingham gal and the only other person I know who used the same name for her granny was from Mansfield. So I think it could be a local thing. Any members use the same. And where do you think it comes from. It can't be French because that is maman,
