Looking for Tompkins Family

Hi
I am looking for any information about my Great Great Grandfather Oswald Freeman TOMPKINS family. He was born on 04 April 1916 and died 30 November 1995. The only other information that i have is that his father was called Frank TOMPKINS possibly born abt 1877 and his mother possibly Angelina FREEMAN possibly born abt 1876.
If anyone has any information it would be greatly appreciated.

Thank You.
