Book (2) Kids Genealogy Book is the history of kids and their family. It is their mother and father's grandparents, great grandparents, and so on. It is often called "The Family Tree." You take the family and place them in order, called generations. The kids are logging down information with their family members. What's different about this book is that the book is aimed directly for the grandparent and the child to spend quality time together and to pass down generational wisdom. It is family history given directly to the child to log and keep track of.
