The Genogram: "A genogram resembles a family tree however it includes additional relationships among individuals. The genogram (pronounced: jen-uh-gram) permit the therapist and the patient to quickly identify and understand patterns in family history. The genogram map out relationships and traits that may otherwise be missed on a pedigree chart."
My wife and I are going to be doing this during this week to better understand our family history and how it affects our marriage and emotional life.
A Genogram is a really interesting excercise for an engaged couple to do to understand the family history they will bring into marriage.
