A "bush" is the best name I can think of. I want to see a tree of all descendants of all the ancestors of a selected individual.

So, I select the individual, the routine would go up the trees to all of the highest ancestors, then show all the descendants of each of those ancestors, in a tree form, top down, perhaps showing the relationship.

The result would be similar to a list of all relationships, showing all the brothers and sisters of the direct ancestors, along with all of their descendants.

I realize the resulting tree would probably be too large for printing, but a screen scrollable layout would be great.
