naming after grandmother

Well This is my second pregnancy and I'm completely torn that my future child won't be meeting my grandmother. She passed away in 2014. Mentally I tell myself that she's always with me as I have a picture in my room of her and I pray to her daily.My daughter had the chance to meet her and be around her... and see her go. She always brings her up and cries, she's six,so i let her process her feelings instead of telling her don't cry, especially when we watch Moana. We can't seem to get passed it.Well we picked names if we were to have a girl or boy.The name we decided if it's a girl it'll be Juliette Mary "Mary" is my grandmothers name. But I just don't know how to tell my family the name I choose as I have 4 sisters and 1 brother, took her passing just as hard. They have mixed personalities, have anybody had negative responses from family members after naming them after a deceased member.I just don't know how to let them know, or worried I'm gonna get some stupid response from them, and cause a argument stressing me out I don't know maybe I'm overthinking it?!
