Hide Columns with Drop Down list

I want to write a macro that will hide columns base on a drop down list. My drop down is located in Cell A3 and contains 6 names. These names are located in each column (C through the end of the worksheet) in row2 (C2 to ???2). The names appear in random order. When I select a particular name from the drop down I want the macro to hide the other 5 names not selected.

So far I've got

Private Sub Worksheet_Change(ByVal Target As Range)
If Not Application.Intersect(Range("A3"), Target) Is Nothing Then
Columns("c:k").EntireColumn.Hidden = False
Select Case Target.Value

Case "Name 1":

End Select
End If
End Sub

But I can't figure out how to write the case to hide the columns I want hidden

I obviously don't know what range goes with which case, but here is how I would do it w/ kind of random conditions:

 
Private Sub Worksheet_Change(ByVal Target As Range)
    If Target.Address = "$A$3" Then
    Range("C:K").EntireColumn.Hidden = False
        If Target = "Name 1" Then
           Range("C").EntireColumn.Hidden = True
        ElseIf Target = "Name 2" Then
            Range("C:E,H:J").EntireColumn.Hidden = True
        End If
    End If
End Sub
