"Do not know that and my client cannot find the original deed"

For my County, you go online to the property map, zoom to that lot or parcel, and there is a pop out showing all owners of record. Or, your client goes to the courthouse and asks. It's public record. So is the tax filing, to see if anyone processed this as gift. And attorneys keep records; your client might not know, but attorneys have records.

Your client needs to do some digging.
