Dear Ms. Bright,
Thank you for posting your request on History Hub!
We searched online and located articles on hemophilia inheritance patterns from the Center for Disease Control and the Hemophilia Federation of America. We also located an article on Medical history: Compiling your medical family tree which may have some useful advice. In addition, you may wish to contact local and state historical and genealogical societies, as well as the Northern Ohio Hemophilia Foundation.
Please note that medical information about persons that have passed away may not have been retained by any organizations, while medical information about living persons will be protected for personal privacy reasons. Also, it is likely that many persons with the condition chose to never publicize the fact.
We hope this information is helpful. Best of luck with your research!
