Best site for this information is www.FamilySearch.org. - LDS (Mormon) Church site. My mother was a Tiffany. Her ancestors joined the Mormons in the early days of Joseph Smith and followed the Mormons from Newfield, NY-Eaton, Ohio-Litchfield, Ohio-Nauvoo, Illinois-Garden Grove, Iowa-Ft. Laramie, Wyoming-finally to Salt Lake City, Utah-Provo, Utah-Salem, Utah settling there in 1859 (it was originally known as 'Pond Town'). Email me if you have questions.
