Searching for letters, journals, and other personal and public documents referencing the life and military service of brothers Israel and John Owens, who served as privates in Company C of the First Iowa African Infantry, later the Sixtieth U.C. Colored Infantry. Israel (born about 1838) died of disease at Helena, Arkansas, in August 1864. John (born about 1841) became a corporal and drowned in February 1865. Their mother, Melinda, filed for and received a pension soon after the war. Any and all help appreciated.
