It turns out my wife does have another Chaffee connection through her Thrall line. Charlotte B. Thrall 1832-1894 married Fredrick Chaffee 1823 - 1891.Their children were Katie Elizabeth b. 1852, Frederick Gove b. 1855, George Thrall b. 1857, and Newman Keyes b. 1868.
If these names match with people in your line, I have extensive Thrall information including a book going back to colonial times , if you are interested.
