Family Echo will print out whatever part of the family is currently displayed on the screen. You can often get the part of the family you are interested in by experimenting with who you click on and the option settings for the number of generations to display for Parents, Children, and Others.
For instance, if I wanted my grandparents, their children and spouces, and their children, I can click on my father and set Parents, Children, and Other all to 1.
