Mr. Goss,
The online Archive of Terrys Texas Rangers at http//www.TerrysTexasRangers.org should be of some help to you. We have a page set aside for JD Owens at http://www.terrystexasrangers.org/biographical_notes/o/owens_jd.htm but haven't added our information to it yet. With 1,200 names to research it can go a little slow at times. I'll see if I can get Misty to move JD Owens up in the queue to have what notes we have added.
