TreeAlive maps family trees. When a visitor's ancestors lived in South Carolina, the markers standing near those places surface automatically alongside their family's journey:
Battle of Fort Sullivan · a few streets from where a family lived in the 1780s · the palmetto-log fort whose walls absorbed the British shells on June 28, 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 South Carolina family sees South Carolina’s).
