middle name help!

Christine • New Jersey. Social Worker. // 25 // Wifey 5.28.16 // Dog Mommy // Matthew & Grant 8.28.17 👶🏼👶🏼
DH and I are pregnant with identical twins! Chances are that they will ether be boy/boy or girl/girl. We have girl names picked out without a doubt and are absolutely set but boy names have been more difficult! One boy name we have is Matthew Reid and the other name we like is Grant...the only thing is we can't think of a middle name to go with Grant. Any ideas?!?
