My G-Grandfather, Joshua Chilton had five brothers. Two were William and Mathias. These two, along with Joshua, were in Wisconsin in the 1830's and 1840's. I have very little on Mathias. I did find mention of a Mathias Chilton in northern Missouri in the middle 1800's. Even this record is sketchy. But I have never found another Mathias Chilton, so I am assuming that is my Mathias (Matthias). Most of the Chiltons that went to Missouri, or so I have read, are descended from the same line as Joshua, William and Mathias.
