Earlier this week I posted a blog about a Roadside Historic Marker that involved the grandparents of Mark Twain. There were a number of conversations involving any database information I might have which I use for my research. This blog will compile a list of my references, by state in alphabetical order.
If you have a suggestion for another index of markers, please let me know in the comments below. I always appreciate database references for my research.
Also, if you come across a dead link in this blog, please let me know so I can update and/or correct. Thanks for your help on this! Some links are used more than others.
There are a couple of index sites which I find useful that include all states, all data. Those would be:
National Parks Service, Register of Historic Places: https://www.nps.gov/subjects/nationalregister/index.htm
The Historic Marker Database: https://www.hmdb.org/

Massachusetts (Cambridge area): https://www.cambridgema.gov/historic/cambridgehistory/historicmarkers/historicalmarkers
