Newspaper name and address, for an obituary

I am looking for an obituary on my great Uncle and Aunt. Their names are Charles Murriel Fowler/or Charley Murriel Fowler and Burley (Coggins) Fowler.
Charles was born Oct.23, 1929 and he died in 95. He's buried in Riverside National cemetary in Riverside, California.Charley's wife Burley died abt 90/91 in Fireball, California. They had two sons:
1. Elgin (Smokey) Fowler and 2. Millie Perry Fowler

I would like to know where to write to get copies of their obituaries, and would also like to try and find their children to write to. I would appreciate any help. Thank you
Sincerely,
Carolyn Potts
