I'm hoping to create an hourglass chart that includes my brother, sister, their spouses and their children, but the best I can do is one that includes just one of us and our children.

Is there a way to create an hourglass chart that includes all the spouses and the offspring of the person and his brothers/sisters?

The alternative is to create a chart that lists all relatives, but this includes branches of the family tree that aren't relevant for this report, and that make the resulting chart far too big and complex.

Thanks!
