My daily Google news trawl for news articles that include the word "Princess" brought up the following article from the Richmond (VA) Times Dispatch.
The article cites AP stories from the late 1940s regarding the case. In the 1980s, I worked for AP as a news librarian, and I made copies of the original stories for my files. It might make a good article for the blog. (But not until after the Hymn Sing on Sunday.)
