Joy L. Zagar was married when she enlisted in the Army in Denver, CO, according to her record in the National Archives, Access to Archival Databases, and in Ancestry. Both sources also give her race as Negro and her birth location as Kentucky. It is not known at this time how Joy L. Zagar self-identified or if her noted race was an error in her military records. She was the wife of Jack J. Zagar, Jr. and the couple lived in Pueblo, CO. Jack J. Zagar, Jr. is enumerated as white in the 1930 and 1940 U.S. Census, and his WWII Draft Registration Card and Social Security Records (both in Ancestry). The couple is listed in the 1942 city directory. [Interracial marriages were illegal in some regions of Colorado, and not illegal in other regions.]
