Question or opinions needed

James
We want to name our baby boy Roland Matthew. For very meaningful reasons to us.
Roland is our oldest sons middle name. He was KIA in Afghan war in '11.  Another young man was also killed with him in the same incident and his name was Matthew. We became somewhat close to his family that lives in another state. We met them at memorials for the unit (this unit lost 22 men) and kept in contact via Facebook over the years. 
So my question or opinions I need is...
Should we ask the other young mans family to use his name for our son? What do you all think?
