Thanks -- all the web sites (FamilySearch, WikiTree, Ancestry, etc) show him as dying in 1835 and being buried in Beuker Cemetery in Missouri, but I haven't been able to find any proof of either the date, or the burial location. I visited that Cemetery in September of 2021, and his gravestone was nowhere to be found (his wife's headstone is there). I've seen the Civil War pensions before as well, but that's a bit of a mystery -- if he died in 1835, that would have been well before the Civil War started (?).
