Ordinarily, you'd expect northerner for the comparative of northern, but there is a very common noun northerner, which may be why the Frenchified "more northern" is the usual form. Again, you'd expect northerrnest as the comparative, but with directions, such as northern and southern, top and bottom, upper and outer and so forth, the superlative is usually formed by adding -most: northernmost, uppermost etc.
