If, as it seems likely, the Calvin Chaffee who was in Genoa in 1810 is the same Calvin Chaffee mentioned on page 87 of "The Chaffee Genealogy," then he was the son of Thomas Chaffee and Hannah Reed. The Chaffee book says this about him: "Calvin Chaffee, born June 9, 1783; died after 1811; lived in Scipio, N. Y."
Calvin of the Chaffee book was the brother of my 3rd great-grandmother, Abigail Chaffee, wife of Amos Watkins. Abigail and Amos are found in the 1820 census of Scipio. Another brother, Zephaniah, supposedly died in Scipio in the summer of 1827 according to the Chaffee book.
