I'm Posting this as a reference to my Grandfather who passed away a few years back, but it gives you an idea of where his family ended up. He had several siblings and many grand children. And of course my great grand parents were Leonard and Dorothy Upson. I don't know a whole lot about this, however my Aunt recently posted on facebook about being from the area where you have referenced (Ubbeston, Suffolk). So I figured this might be of some use.
Yakima Washington - In loving memory of Jerry Dobert Upson who passed away at Memorial Hospital in Yakima on July 7, 2006 after a short illness.
Jerry was born in Ava, Missouri on September 14, 1933 to Leonard and Dorothy Upson. As a young boy Jerry worked alongside his father cutting mining props in Wyoming, Utah and Montana. In 1945 his family moved to Selah. He attended school in Selah and also worked alongside his parents in the orchards. At age 18 he went to work for the Southern Pacific Railroad. During that time, in 1954, he met and married the love of his life, Kathleen Hess
