D. C. Parker

I am trying to find relatives that may be able to provide information on my family tree. I can go back to D. C . Parker (my Great Grandfather) who was born February 14, 1885 in Texas. He died February 6, 1964 in Avenal, Kings County, California. He was married three times, with his first wife Beula he had four children, Robert Elmer, William Earl, Zelphia, and Howard. I have not been able to find any details on D.C or Beula. I have been told that I am related to Bonnie Parker as well as Cheif Parker. I have not been able to confirm this as of yet. I also have Luberta (Berti), Frank, and Robert as siblings to D.C. Any help is greatly appreciated.
