Moses W. Addington I've got him as having died on 8 November 1908; buried Pine City, WA.
I have his wife as a Thompson instead of Thomason.Might be a misspelling somewhere.She was born 3 July 1839 in Georgia and died 16 April 1901.
His siblings were: Henry (b. Feb 1818) Rachel Matilda (b. 1 April 1820) William Riley (b. August 1822) Joseph Huckabee (b. 14 December 1824) James M. (b. April 1827) Moses W. (b. 1832) Mary Elizabeth (b. 1835) Altha "Alphey" (b. 1838) Harriett (b. 1840)
