Saints Who Left Descendents is a book written to help the reader find his or her Saints in their background. The idea is to find some sort of Ancestor, a Saint or any nobility from Europe and match that Ancestor with one in the book.

In the book there are about 110 Saints and a listing for each one includes Descendents who are nobility, royalty, or saints, and also a section on Ancestors. There is a listing of the family of the Saint, parents and siblings, as well as a listing of a biography that explains what the Saint did to get raised to the altars.

The Saints are arranged by century, and at the beginning of the chapter is a time line and a listing of the Popes that served during that century.

The author is an engineer who passed the mensa test and has studied genealogy for years. He is a member of the International Society of Charlemagne, the General Society of Mayflower Descendents, the Sons of the American Revolution and many other Genealogy based Societies.
