I'm not sure specifically who 'Tamar Judah' is without more context. There could be many people named Tamar, and the 'Judah' might be related to a family or place in the story. It could be a very specific narrative within a particular community, culture or even a family's own history.
The story of Judah Ben Hur is a mix of fact and fiction. Some parts might draw inspiration from real history, but much of it has been creatively crafted for entertainment purposes. We can't simply say it's completely true or false.
I'm not sure exactly as it's not a very common or well - known specific story title to me. It could potentially be a fictional story that combines elements of heaven, a lion, a bear, and a unicorn, perhaps about their experiences in a heavenly realm or something similar.
As I don't know the specific 'Tamar Judah story', I can't say for sure. But generally, a story's main plot could involve Tamar Judah facing some sort of conflict, like a struggle within the family, or a problem in the community. It might be about her achieving a goal, or learning an important life lesson.
