Does anyone else with Madison Co AR ties have Ocular Albinism in their family? OA is an X-linked recessive characteristic. I've traced mine back to a great-grandmother (Amanda Gibson Walls) who was born abut 1870 in Madison Co AR. Her mother was Louisa, but I'm not sure what Louisa's maiden dame was or who Amanda's father was. It occurs to me that there may be cousins out there who have the same condition. If so, please contact me.
