Shaun- Hi, cousin. There is no Theodore Roosevelt Chaffee in "The Chaffee Genealogy", 1909, by William Chaffee. To be expected, since it was mostly compiled in the 1890's and Teddy was not yet famous, and could not expect a namesake that early. Further, there are 141 citations of "William" Chaffee in the book. Can you get spouses, places, dates, details?
