When you hover with the mouse over a marker a "tooltip" will show with the name of the location.
When you click on the marker you will see two links.
The first link will open a new browser tab with the Wikipedia entry about this location (if such an entry exists).
The second link will present (in the Info Window itself) a list of all persons born in this location.
The names in this list are clickable and will open a new browser tab with the family page of this person.
