Loretta Janson 1917-1938

This was mom's favorite and only sister, Loretta.  She was 2 years younger than mom, and she died at 21 years old. I think mom missed her all her life. 

Yesterday, at the Minnesota History Center in St Paul, I found her death certificate.  Mom always said Loretta died of rhumatic fever, and I suppose some of the symptoms corespond with what's written on the certificate, but acute nephritis is kidney failure.

Any medical types reading this could leave a comment, ok?
