There is much info on the JETTS as Rangers, etc. One source: 'Veteran Biographies of the Herzstein Library in San Jacinto'. I've been to the 'TX Rangers Museum in Waco, TX'; they didn't have anything at least on display or about the Jetts, but doesn't mean they don't on file. I haven't followed up as still working on genealogy outline for 4 lines in my TX husband's family. (FYI: 'The Lone Ranger' was based on the life of TX Ranger JOHN REID)
Would you like quick lineage summary, first?
