Gay Mathis wrote me with a correction for the post on April 1, 2010 Historical mistakes can definitely be a plus. Gay, an expert in the field of genealogy, writes
Isaac Newton Wilcoxen actually died 10/20/1910 and was buried 10/23/1910 in the G.A.R. Cemetery per Funeral Notice 10/23/1910-Seattle Post-Intelligencer..Also, see WA State Death records, and Civil War Pension Card for death date..
Thank you very much Gay!
