TreeAlive maps family trees. When a visitor's ancestors lived in Kansas, the markers standing near those places surface automatically alongside their family's journey:
Hollenberg Pony Express Station · near where a family homesteaded in Washington County in the 1870s · the ranch house four miles north, built in 1857, is believed to be the only original and unaltered Pony Express station
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 Kansas family sees Kansas’s).
