TreeAlive maps family trees. When a visitor's ancestors lived in West Virginia, the markers standing near those places surface automatically alongside their family's journey:
Berkeley Springs · near where a family lived in the 1770s · the springs Washington first visited in 1748, made a town in 1776
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 West Virginia family sees West Virginia’s).
