Massachusetts's 1930 Tercentenary markers, on the maps of their own eras

For the 300th anniversary of the Bay Colony, Massachusetts cast 275 roadside markers in 1930 with inscriptions revised by the historian Samuel Eliot Morison. Every one now has a permanent page at TreeAlive, placing its 1930 text on georeferenced maps from the period it commemorates.

What a Massachusetts family sees

TreeAlive maps family trees. When a visitor's ancestors lived in Massachusetts, the markers standing near those places surface automatically alongside their family's journey:

Samuel Lincoln House · near where a family lived in Hingham in the 1600s · Samuel Lincoln, ancestor of President Abraham Lincoln, purchased this land in 1649

A marker stops being a roadside plaque and becomes a destination with a personal reason to visit. Open the live demo tree, choose the Crossings tab, and turn on Historical Markers to see the experience working (the demo family’s markers are in Pennsylvania; a Massachusetts family sees Massachusetts’s).

QR-ready, from day one

Every marker page has print-ready QR artwork. A scan at the sign opens the marker's page on the period map, no app to install. The artwork files are available to the commission and its sign vendors; TreeAlive does no printing or installation.

Marker page links are permanent: identifiers are never reassigned, so a code printed today resolves for good.

Cast for one anniversary, ready for the next

These markers were themselves an anniversary project: the Commonwealth's gift to its own 300th birthday in 1930, from Plymouth's boundary stones to the sites of the Arbella landings. As America's 250th approaches, each 1930 story can live as a linked set of marker pages on maps of its own era, the same maps our visitors already explore through their own family history.
