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.
