Altho I didn't find an obit for either Carl or Jean, I did find the cemetery they are buried in.
They are both in Forest Lawn in Omaha. Carl was buried 16 Sep 1968 and Winifred on 13 Nov 1997.
Could not find them on Find a Grave, but did a google search for Forest Lawn Omaha, brot up the page for "P" and scrolled right to their names.
Then I tried omahaobits.wordpress.com/ , but was not able to find their names.
So did a google search for Greater Omaha Genealogical Society. They used to have an area where you could contact them....if you knew the cemetery where someone was buried in Omaha, and the date of their burial, they would look for an obit. Well they no longer have that capability.
