Looking for Ulysses Simpson Speakman Pappy Line with Other Wife Not Mary Hall

I'm looking for information for the family of Ulysses S. Speakman and his other wife.... My family line is from his union with his first wife, Mary Hall. I have heard some are in Arizona and Colorado but don't know for sure.
If you have information please contact me at tuathadana@my.tupperware.com

Thank You.
