The House of Isilviere

[X-IHH (Murphy)]

So, I was re-reading through the Regent's Guide, and I noticed that the description of the first BR game involved someone named Wilfred Isilviere, and then I looked at my character name and the light bulb went on.  What's the relationship there, or is it a coincidence?

Wilfred is the illegitimate son of your elder brother, the (now deceased) Count Isilviere of Fairfield. Wilfred left home many years ago. You nephew is now Lord Isilviere.
