I am looking for my birth fathers family after 26 years of life not knowing them. I have certain bits of information about them, but nothing exact. What I do have is information on my father. His name is Mark Edward Spangenberg. He was born on July 31st, 1962 in New Jersey (exact location unknown), he died on May 15th, 1988 in Arizona (Phoenix area, no obituary I could locate). He was survived by at least 3 siblings, all older. Two sisters and one brother named Charlie. I know his SSN from the social security death index. I'm looking for more. I want to know this side of my blood. Any help is greatly appreciated.
