Because it is time consuming you may have to undertake this task on your own. If the family really owned the property there will be a record of it down at the county building. You have to ask --many on staff are helpful --but you can look at the title history of the property. It will take some time. Some of the old files are still in books-not on computer or on microfiche --it could take hours or days to find what you are looking for. Or you can pay for a title report--depending on where you get it from can be less than 200 dollars. Good luck in your search.
