It's pretty much a toss up. I just did an informal tally of the first 87 NC soldiers who are listed in Greg Coco's book, Gettysburg's Confederate Dead, who were reinterred from the Gettysburg battlefield itself. Of this number 40 were buried in Oakwood and 37 went to Hollywood, nearly an equal split. So either cemetery would be an appropriate spot. However, it does appear that many of the unknowns wound up at Hollywood.
