UNIONROCK ROYALTIES III LLC, Karnes County, Texas
Mineral interests on the Karnes County Appraisal District's 2026 certified roll.
The same name and mailing city appear in 3 other covered counties. DeWitt County (9 interests) · La Salle County (17 interests) · Live Oak County (41 interests). 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 UNIONROCK ROYALTIES III LLC may hold interests elsewhere that this page cannot show. Absence is not evidence.
