In 1940 in Rochester, Olmsted, MN is Hilda C Hoglund, 42, single in the Rochester State Hospital. Says she was in Minneapolis in 1935.
On the MN Death index is Hulda Charlotte Hoglund 28 Feb 1891-17 Feb 1974 in St Louis county, MN.
So there's a few Hilda and Hulda C or Charlotta Hoglund, but birthdates differ. None match perfectly.
