I realize this is an old post,but did you locate the information on John Harper? I've been building a tree on a John Harper born in abt. 1773 in New York, lived in Batavia from at least 1810 through 1832, then moved to Emmett Township, Calhoun County, Michigan with his eight children (including Hiram, Benjamin, and Napoleon B.). He married Rachel Barnum (not positive on the last name). Please contact me at e-mail address: firstname.lastname@example.org
