How to verify mineral rights in Jefferson Co

Our family have documents indicating oil and gas (mineral rights) ownership in Jefferson Co. TX. Where do we begin to verify this information? How do we find out if this ownership still exists or has been sold ? We have the web site co.jefferson.tx.us which verifies our interest, however, we are unable to tell if the mineral rights have been sold or are still in our ownership. Suggestions are welcome. Thanks!

I think you will need to research the title to see if minerals were retained.

I would go to Texasfile.com and search for the family name (assuming post 1952)

you could also look at courthousedirect.com or go to the courthouse and search the books…

if you are comfortable answering what was the landlowner’s name?
