My brick wall is my second great-grandfather, Robert C. Boyd.  He was born 1818 in Ohio, married Anne Johnston, and died 1862 in Ashland County, Ohio.  I think his father was John Boyd, Jr., born between 1794-1798 in Westmoreland County, Pennsylvania who married Ann Baine in 1818 in Wayne County, Ohio.  But I can find no definite proof.   Lola Castor Thompson
