My name is Luke Sprague and I write family history books.

On April 10, 2017, I published the Schultheis Odyssey: From Bavaria to the Pacific Northwest, a 326-page hardcover contextual history of the Schultheis family of Colton, Washington.

Here is a picture of me with the Schultheis family​ after receiving their books:

Here is the cover of the book:

And here is just a sample of what the family said about this book:

I am not someone who likes to read for enjoyment, yet I found myself reading this book and having a hard time putting it down! Your style of writing certainly keeps the book interesting. Thank you for all your work. This will be a treasure for all of us."

Margaret (Schultheis) Imrie

I am almost done reading the beautiful book you put together. It is magnificent. You are a real artist.”

Anne Schultheis

You did a really good job on that thing. I sat down and read the book all afternoon. What a treasure! I am going to order one for each of our four daughters."

Dave Schultheis

The family is much indebted to Mr. Luke Sprague for his professional and creative work in bringing together many elements of this history. Luke discovered many features of this family odyssey that I was not aware of and had never heard recounted during family gatherings."

Michael Schultheis, SJ

I saw your beautiful Schultheis book at the library this morning while I was there. What a wonderful book. You must be so proud. It is very impressive...Either way, job well done!"

Monica Peters

I've been looking over your beautiful book. I'm so pleased, a person would think that my own kid did all that wonderful work!!"
