Help with baby names for my quadruplets?

Im asking of my sisters Loren's account,Im Jessica. Im expecting my quads the 24th of May! im having three girls and one boy! i already have 5 yo twins Amelia Grace and Jace Michael and im naming one of my girls Ruby but im not sure on a middle name. So suggestions please! im ok with pretty much any name without the letter 'V' in it so long as they're cute and age well.
