I didn't find James death info.
Gladys K. Johnston
Born: 19 March 1914
Last Res: Grand Rapids, Itasca, MN

I'd look for her obituary at the Minnesota Digital Newspaper Hub, www.mnhs.org/newspapers
If that doesn't work out, you can order a copy from the Itasca County Historical Society, www.itascahistorical.org/genealogy/
