Stepp-Stapp Family Books
The 2 most common books written specifically about Stepp-Stapp surnames are The Stepp/Stapp Family of America, by Henry P. Scalf and The Stepp Family Chronicles, by William Wayne Stepp.  Unfortunately, Scalf's book is no longer published, and it is quite hard to find a copy for your personal library.  The good news however, is that The Stepp Family Chronicles is still available for purchase.

The Stepp Family Chronicles, by W.W. Stepp           
If you are interested in purchasing The Stepp Family Chronicles, you can call,  email, or write Brenda Stepp White or David Lee Stepp and they will have a book off to you the next day!

The cost of the book is $43.00 ($40.00 for the book, $3.00 for shipping and handling), and is well worth the information held within. Wayne Stepp has spent many years and quite a fortune researching the Stepp-Stapp Families and this book is a massive collection of all his work, even going back to the ancient Russian Steppe lands.

The following are 2 excerpts from his second edition:
