Heather, You can find some of that information in the book Orlando a Centennial History by Eve Bacon.page 155. On Feb 21, 1870, Sheriff David Mizell was ambushed while crossing Bull Creek at a spot forever called The Mizell Ford.Needham Yates was one of the first to be apprehended as a suspect and Jack Yates his brother.He was the son of James Yates and Agnes Rowland from Duval County. Black Creek District.
This is also a good referance book for informaton on your family.
Another good book is THE WAY IT WUS.It is about Mose Barber and Yates and others that he was associated with.
Also read Old Tales and Trails of Florida and Ox Cart in Florida by Myrtle Hilliard Crow.She has stories from Pionners who lived in that area of Florida in the 1850's.You will enjoy this book. Also read Bones Mizzell, Florida Cowboy.
I forward your request to a Yate/Bass Cousin who may be able to help you on the Yates family.
