Thanks for the info. Wish I was 30 years younger. I live in New York State, and over 20 years ago, I spent many days in Boston doing research on the 54th and 55th Massachusetts Regiments at the Boston State Archives and the State House archives, the Boston Athenaeum, the Mass. Historical Society, Harvard's Houghton Library, and elsewhere in the State, ie., Massachusetts National Guard Museum & Archives in Concord, as well as the National Archives in D.C.
Here’s examples of the sorts of information MA will give you. And it’s organized beautifully. There are all town books in all libraries that copy out the information from the original town books.

Rhode Island isn’t as good, but still not bad. They scooped up all the data at one time, then later they scooped up what they hadn’t gotten earlier and published that next; then again, then again. So you have to go to multiple books for particular information.
New York is just genealogical disaster on the hoof. If you go into the town halls, you can see stuff but that’s a lot of traveling. It felt like I lived in the trailer at the Albany library for a while, it seemed trying to copy out Dutch info. Eyes crossed. And spent a lot of time in research institutions all across NY.
