Bill, I don't know of any on video; perhaps a search for "The Tiger's Coat", 1920 might lead to an archive. She was in a couple of other films, "I Can Explain" and "Riding with Death" around 1921.
I wonder if any of these or any of her movies are around any more. Weren't many silent films made of stock that would lead to self destruction with time? They were fire hazards.
You should contact UCLA film department. I understand that they are very active preserving old silents and post WWII films. Someone from there should have a good lead to her films.
