I don't have obit, but there is a photo of him on familysearch.org..... John Marvin VAN DAMb 1917 Paterson NJ...Brazilian Immigration 1938. He was back in NJ 1940, with parents Peter [police officer] and Inez [their only child]
From public records it looks like his wife is Carol M b 8-15-1917; dau? Kim E b 6-15-1957 who m. Wm MILLER 10-9-1983 Los Angeles.I'm assuming this marriage failed, if she is listed as VAN DAM on later records. All 3 are listed for the same address in Tarzana.
