Hi Wes, I did find a family tree with Everald and Marian and asked the author to contact you.
I didn't find anything for Marian and there are too many Robert Dudley's. Do you know where and when he was born?
Everald died 18 June 1991 in Shasta Co. You can request a copy of his obituary from Random Acts Genealogical Kindness. Go to www.raogk.org, read guidelines, choose California, choose Shasta Co. and choose volunteer.
