Greg, I went to the link I posted above, put in the book and page of the deed you shared (402 - 472) and found wills, just like you did. I think I understand that part. The deed you shared is old, and is evidently not in their online system. Many of the counties around there have that situation. Many of them started using the computer for their deeds etc in the 1980s and later, so those documents are in their computers and those are easy to get online. The older records need to be scanned and verified and put into a database. Maybe if you were in Harrison County you could use their on site computers and see these deeds, and of course look at the old books. But these are not in their online system. I know that Tyler county has a similar website, and there is a way to download software to access their old system. Somebody on this forum told me about that, and I have used it. I don't know if Harrison has this, but if you have a chance you could call them next week and ask. If you find out, please post the information for others.
Meanwhile, going back to that system
Harrison County WV County Clerk documents
choose Individual and put in your greatgrandmother's name. You'll find several documents. That is what I was referring to; if you look at the tracts there, and compare them with the tracts listed in the deed you posted, you can see if there are any tracts not sold in those tax sales.
A lot of hunting around.
You probably could order those deeds from the county.

There might be a statute of limitations involved.
If you want an attorney to check into this, I know of one in a nearby county. He might be able to help.
