You might also find the book, Queen Victoia’s Gene by DM Potts interesting. The author suggests a quite surprising theory as to how Victoria came to carry the gene and how it became a major factor in the downfall of the Spanish as well as the Rusian royal families.
My son has a form of hemophilia so I have a avid curiosity about the disease.
Rusian should be Russian.
I'm wondering if the theory you heard about Queen Victoria was that she must have been fathered by someone other than the Prince? I heard that he did not have hemophilia, nor did his family have a history so it would have been impossible for him to really have been her father.
I will check it out.
Also, to Leni, please check my post and make any corrections. I would love to see the collection.
