I need advice . I'm having twins and we are giving baby b my fiancées grandmothers name as a middle name . I wanted to do the same with baby a , using my grandmothers name but my mother and grandmother have the same first name (dolores) . So I opted for my grandmothers middle name to give the baby which is blaniece (which I don't like). Should I name the baby after my grandmother even though I don't like the name to make it fair ???? So that each baby has their great grandmothers name as their middle name Or should I just stick with the name I already have .
