What do you think, Pierre or Elijah?

Okay, so my mother is so thrilled about her technically second grandson, she wants to pick his middle name and has decided she's in love with the name Elijah. My boyfriend on the other hand is in love with his own middle name and wants the baby to have the middle name Pierre so that he and baby can share initials because the baby does not have his first name. this our child and that is my mother, what should i do? Ashton Elijah Collins, Ashton Pierre Collins, or what the heck, Ashton Elijah Pierre Collins? help me please!
