You didn't mention where you thought they lived, but on a lark I checked the Illinois Statewide Death Index at the Illinois State Archive Web site. From my own research I know that many were homed out of Chicago or nearby.
I found a Charles Edwin Popham, died 8/19/1950 in Coles county, IL at the age of 90. There was another Charles H Popham died 7/11/1943 of unknown age in Winnebago county.
Veazey was not as clear. I find 2 spellings, Veazey and Veazie. There are no Wilbur's for either, but there is a William T. Veazie, died 3/26/1945 in Chicago, of unknown age.
I hope that helps.
