The main Old Bostonian Association web site is the place to find out about the Old Bostonian Association and events it puts on for you. There are also news feeds on Boston Grammar School and particular old boys. If you know about anything that’s happening that doesn’t find it’s way on the web site, drop me a line or post a comment here, complete with a web link to the story if possible.
The OBA Wiki Project is the place to find “historical” information about everything connected with Boston Grammar School from 1555 to the present. You can even create yourself an account there and start contributing. The Community Portal can give you some ideas of how you might be able to start helping right away.
