Derral Dean Mosby of Ridgefield, WA., was born August 29, 1955 in Cottage Grove, OR – passed away July 1, 2020 in Ridgefield, WA. Derral lived his entire life a true representative of the Cowboy Code. Virtually born in the saddle on the Mosby Family Century Farm he was a successful sheep & cattle rancher, all-around champion rodeo cowboy and a well-respected cattleman. The only thing he loved more than his much beloved Registered Horned Hereford show cattle was his family. Survived by his wife of nearly 47 years, Tomi Mosby; daughter Staci De Jong (Jerry) Lebanon, OR; "Poppy" to grandchildren Trevor & McKenzie Turner of Battle Ground, WA; Taylor & Logan De Jong of Lebanon, OR; and Dawsyn Mosby of Centralia, WA. Preceded in death by sons Derral K. & Chance and daughter Lacy. Friend and mentor to many Derral was truly a one of a kind, irreplaceable man taken from us suddenly and far too soon. Celebration of Life will be held July 18th on the ranch, as he would have wanted.
