I could easily do lookups and forward the information. However, that will not produce development of your research skills. If you don't mind, I'll do a little of both and still achieve the objective-family history? First, most men born 1871-1900 registered for WWI Draft. That's usually a good starting point when trying to find them in 1920. Registration took place in 1917 and 1918. Leslie and Raymond Dewey registered in Llano County. Walter registered in Nueces and Alfred registered in Lampasas County. On your tree, Walter needs to be relocated as the son vs father of Jonas. If you haven't already, logon
https://familysearch.org/ and setup a "free" user account. That's necessary to access vital records. After completion, click "Search" in the header. When the template opens, click highlighted "Death" then enter Texas in "Death place" box. Click highlighted "Parents" and enter Jonas Beford as the father. Click "Search" and Walter is first on the returnees. Note his mom's name then enter Julia in the appropriate box and click "Search" once more. In addition to Walter, you should have access to: Leslie Bedford, Ollie Lee Barker, and Ida Reynolda. Ida incorrectly programmed and should be Reynolds. However, you'll have to be content with the error. That'll get you started. The other siblings, Raymond and Alfred, died in Contra Costa CA thus unable to access their certificates.
