Progress got stymied a bit, due to my knee injury. While my archives contain a wealth material, there is always research to do.
It was interesting to review Book A of Brands, Lassen County. The first brand recorded was for Thomas Watson on October 20, 1864. The John Theodore brand JT was recorded on May 23, 1889 and never changed for over three generations and appears on the wall at the Pioneer. The same can be said for Hulsman Ranch brand though it was not recorded until 1917, when the State of California began enforcing the recording of brands.
Additional brands have also been included in the original list: George and Mayda Elledge, Hostetter & Johnson, Abner McKenzie and Coit Stone.
