Boy number 3 naming struggle

My husband and i can not agree on a name for our 3rd son. The problem is largely due to the fact that we have do many boys in our family that most of the names we like are already taken. Just to give you an idea of our style our other boys are Christian David and Liam Gabriel. Other names we like ( but can't use) are Leland, Hunter, Henry, Charlie, Easton and Jeffrey. Names we are considering but not totally agreed upon are Reid or Blaine. Please way in or make suggestions.. Also we are trying to steer clear of Sh names because our last name starts with Sh. Thanks!
