There is also a thoery about Anne Boleyn’s miscarriages that I think is interesting. The theory is that after she delivered Elizabeth, she developed problems with the Rh factor.
The old theory was that he suffered from syphilis, which used to be known as "The Great Pretender" because it could produce so many symptoms. I don't know if anybody's dug up ol' Henry, but syphilitic lesions on bones are diagnostic.
Thank you, I couldn't, for the life of me, remember what it was called, but I had that with my two children. I received a shot after the first one which prevented any problems with the second.
