(I'm not sure what either of my grandfather's mothers names were (we have a much stronger desire to honor the grandmother's side of the family, as both of my grandfather's were not the greatest of parents, but my grandmother's are both amazing). I should find that out anyways though.)
Paternal: Frances Anne
Martha and Antonia. Perfectly lovely. My great grandmother was Laura.
I don't know my maternal's (she lives in Taiwan and I've always just called her grandma in Chinese)
but my paternal's is Yvonne Gertrude
Names in parentheses are the birth names, changed when came to US.
Maternal Grandmother was Jennie (Sheindel)
Paternal Grandmother was Ethel (Eidel)
DH Maternal gm was Marie Xoa
DH Paternal gm was Fanny Isabel
Gloria - I really want to love it enough to use it, but I'm just not sure. Have recently considered Gloria nn 'Lori'.
Betty - nms unfortunately.
Lulu - would maybe use as a nn for something or honor with a Lola or Lila.
Maternal: Ione Marie (EYE-own)
Paternal: Vivian... oh my goodness I don't know her middle name.
Ione's sister (that I knew of) is Bernadette. I plan on using those two as middle names for my future daughters (hopefully!)
