Baby boy names

Lyndsey • 23. Have a 16mo son and due with baby boy #2 feb 2015 ??
We decided on the name Logan. But we are stumped on a middle name! What goes with Logan?! Our first is Emmett Alexander. My hubby's name is Kristopher George. So we don't want any of those names. Our grandparents names don't work either :/ helppppp
