I am looking for a limk between the family of Jacob ERBAUGH borm 1797 and the family of John (b. 1808) Mary (b. 1812) SHEARER. Both families have the same genetic eye disease.
Jacob was from Rockingham Co. VA and moved to Montgomery County OH in 1834. His mother was Esther Funk. It is not known if she had the disease or not. She died in VA Her mother's maiden name was Showalter.
The Shearers eventially ended up in Iowa. It is not known which of the two had the disease of if it goes back farther in the family. I don't know Mary's maiden name.
Thanks for any help.
