Delaware's historical markers, on the maps of their own eras

Markers from the State of Delaware Historical Markers Program now have permanent pages at TreeAlive, placing their full inscriptions on georeferenced maps from the periods they commemorate. The Delaware Public Archives has drafted the text of every state marker since 1931.

What a Delaware family sees

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

Block House · a few streets from where a family lived in the 1850s · the 1654 New Sweden blockhouse at Naamans, the only house remaining from the Swedish colony

When a marker stands near a place in your own tree, you have a personal reason to go see it. 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 Delaware family sees Delaware’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. TreeAlive does no printing or installation.

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