• Family trees grow by defining relationships
  that new members have to existing members within
  each tree
• Parents
• Children
• Spouses/Partners
• Unique IDs are assigned to each new member
• Relationships are defined automatically

• Every family member of a tree can become the
  focus of tree display

• Descendants
• Family trees can be multi-dimensional
• The system encourages a unified effort to tree
  development instead of multiple trees
