Try contacting the Register of Deeds Office at the courthouse. They can check the grantee index and should be able to come up with the legal description of the land and from whom it was purchased (grantor). They can also search the grantor index, which would then cross-reference to whom your grandfather sold the land (grantee). Be sure to give them approximate dates for purchase and sale (no more than a 5-year range for each). These records would also indicate if the property passed to another through inheritance rather than sale, which could then lead you to probate records. I presume there would be a fee for this information, but I don't know what that fee would be.
