I came across the SD thing when looking up her funeral because reasons these last few months. Since she also died in the summer, her not wanting any embalming (or autopsy) was one big reason why Amalie didn't have the time to wait for Fritz' instructions regarding the manner of the funeral and organized it post haste herself. (It's all in Lehndorff's diaries; he was one of the coffin carriers, and she was rather heavy.)
