Colour identifies a proved family, a candidate reconstruction, or a record-only locality cluster. The pin details state which kind it is.

Country, county and regional points are representative locations and are labelled as such; they do not assert an exact residence.

What is included?
All in-scope One-Tree profiles are included. Where birth is absent, adulthood is conservatively estimated from a marriage or death record. One selected profile event is mapped per person and region; independently researched deeds, registers, probate, graves and similar occurrences remain separate records. Profile fields are research leads, not proof. Country, county and regional pins are representative points.
