Does anyone else have minerals that have been leased in PSL Survey Abstracts w/ Grantee Casey and Jones

Greetings:

Trying to true up my grandad's minerals. His ledger indicates he had interests in the following abstracts (all school sections): A-5467, A-5468, A-5469, A-5470 and A-5471. If anyone else has minerals in these legals could you ping me. His records indicate a 1/4 interest, so I figure there must be some other minerals out there in addition to the 1/8 the State retained.

Cheers.

What County is this in?
