Hometown Hero

Hometown Hero is an achievement/trophy for the Fallout: New Vegas add-on Lonesome Road. To obtain this achievement/trophy, you must simply complete Lonesome Road.

Noting the name of the Achievement, it is possible that the Courier was born in the Divide. Also, this could be possible as it is suggested through dialogue with Veronica Santangelo that the Courier does not know where they were born. This is purely speculation at the moment and has not been confirmed by any canon source.
