Miller, Suzanne, "Re: Death date for Beulah Chittenden Lyon," e-mail to author, 9 May 2005, notes that the "Lyon County Cemetery Book" lists the date as Feb. 6, 1821, and states that is the date on the tombstone. But states that a copy of Chittenden Lyon's Bible she received from another descendant shows the entry "Beulah Lyon, his mother, near Eddyville, February 5th [could be 6th, as there is a smudge over this part], 1824, the 60th year of her age."
Lyon, Chittenden letter to Witherell, James, 5 Apr 1828, shows she survived her husband by 18 months.
Lyon County Historical Society, Cemeteries of Lyon County, pg 277, shows date, as Feb. 6 (?) 1821.
