I just read an interesting piece by a distant relative of Warner Orland about him. Here is the piece:

"The Swedish genealogist Sven-Erik Johansson has specialized in the digitization of the church records in the region of northern Sweden where Oland ... came from and has published an ancestor chart for Warner Oland going back 5 generations."

I am glad that I ran across this website. My brother and I are huge Charlie Chan fans. I look forward to reading more.
