You appear to be the sole owner of record.
The tax records also show you as the only addressee on the tax bill, although that is not always the best indicator.
When Joe Proctor notarized the deed on 11/9/09, and the wittnesses signed that they wittnessed it, you are the grantee and she is the grantor.
I think you can be at ease that you are the only owner.
There were many deeds before the one to you and your ex, but none of those provide any ownership to any previous owners if that deed has been completed and recorded correctly.
