Hi Julie,
I am very interested in what info you might have on William Marion Cass Jr b. 1877 that was married to 2) Mattie McDonald b. 1885. I believe you have the order of wives reversed. Grace died in 1910 and William married Mattie in 1913, I am related to one of William and Mattie's children, would like to hear from you. How are you related?
Becky
