Many thanks for your efforts to take care of Everett's grave and tell the story of his ill-fated flight in May 1944.
He is my second cousin, twice removed. I have photos and some information about his at http://trees.ancestry.com/tree/22071990/person/1179693386
. I'm not sure if you will be able to see that if you don't have an Ancestry.com account so please let me know.
There is a photo of Everett also at http://www.chippewavalleyww2.org/Veterans/B/Bu/BushendorfEve...
. However, some of my cousins have posted better photos of him on their ancestry.com family trees which are now linked into my account.
I know Everett's daughter but haven't corresponded with her in almost 10 years. I'll try to reach her and put her in contact with you.
