Can click on the lines to see what the connection is, that is, the line shows where a person lived and worked. You may have to zoom the map to get the right popup. Sometimes the popup for a (not so nearby) point and not the line comes up. Can be difficult to tell whether the popup is about a person (work and residence) and just one of those.
