Ooh, a family mystery! Open My Family Story → Map and add someone with + Add someone. Places where your families crossed glow, and Did our ancestors ever meet? under the map lists every crossing, the same-time ones first. For example, you might find your great-grandad and your wife's great-grandmother were both in Barking in the 1840s – they may well have passed in the street.
