I have a book called "The Civil War Veterans of Old Imperial Calcasieu Parish, Louisiana" (Which includes Allen, Beauregard, Calcasieu, Cameron and Jefferson Davis Parishes), which lists over 1400 burials in that area. Henry Whittemore is not listed. That doesn't mean he was not buried in this area because many Confederate graves have lost tombstones or never had them. Also, he may have been buried somewhere else.
