For those who are interested, there is a new book on the life of Kid Lavigne out in the marketplace. The book is detailed at http://www.kidlavigne.com/. It is titled "Muscle and Mayhem: The Saginaw Kid and the Fistic World of the 1890s." As far as I know, it is the first book on a fighter who was arguably the first World Lightweight Champion.
It was written by Lauren Chouinard, whose mother was Kid Lavigne's second cousin a few times removed.
I have corresponded with the author and will be updating Lavigne's record on the site over the next few weeks.
