in
the Navigation box open the site map and then expand all in the
hierarchy view. This allows you to see all the individual descendants
in tree form, allowing you to follow any thread you like.
At the
top of each page the links show the descending line, while at the
bottom of each page the links lead to the children of the individual
you are viewing.
If you want to find an individual, it is better to use the Google Search Site engine at the top right.
