You might try contacting the Pottawattamie County Courthouse in Council Bluffs, Iowa; they have death records. Or, since you know he died in Pott. Co. in 1923, have you tried getting an obituary look-up? That may tell more about him. If you need help getting an obit, please let me know, and I can obtain one for you if you know the date he died, or close to it. Also, if you're looking for parents, etc., have you tried searching census records to make a link to parents? Or perhaps cemetery records? Please let me know if I can help you in any way.
