Finding the year erected

So the sites I’ve been going to are hmdb.org (historical marker database) or historical-markers.org.

I checked and they don’t necessarily have the new ones listed.  A couple, such as Pocahontas (2001) are listed, but other markers appear to be more recent than when the site was updated.

My suggestion is to contact the VA DHR.  From the DHR historical marker FAQ page:

If you have questions or need additional information, contact Randall Jones (804-367-2323, ext. 117) or Francine Archer (804-367-2323, ext. 120).
