The same name and mailing city appear in one other covered county. Galveston County (1 interest). A shared name and mailing city are strong evidence that this is the same owner. They are not proof, and the appraisal districts do not share an identifier.

This is one county, not this owner’s holdings. The site holds mineral rolls for 114 of 254 Texas counties, so LEWIS GWINN MCMAHAN INV TR may hold interests elsewhere that this page cannot show. Absence is not evidence.

4 of 5 interests are on the map, across 1 abstract. An interest is placed only where the district’s legal description names an abstract this site can resolve. The rest are listed below without a location — that is a limit of the description, never a claim that the property is outside the survey grid.
