Rosenberg Library in Galveston has an extensive microfiche collection of old Galveston area newspapers. I don't know if they do searches for anyone, but you might try writing the Archivist at the library. I'm sure a letter just addressed to; Archivist Rosenberg Library Galveston, Texas 77550 would get to him. I would be sure to include a sase just in case, and maybe offer a donation for his time and work.
