Hughes, Thomas and Ada

I am looking for the relatives of Thomas J. Hughes and Ada M. Hughes who lived, died, and are buried in Maricopa County Arizona. I have their death certificates and burial plots.  They had one daughter, Norma Elizabeth Hughes, born in 1906.  Norma had a son, James Edward Smith, born in August 1924.  James was adopted to a family in Phoenix. 

I have James's birth certificate, the original adoption papers and his information through his death in 1985.  I have all the adoptive parents's information, too. 

My last information on Norma Elizabeth Hughes is the 1930 census in which she is listed as living with Thomas and Ada in Phoeniz, AZ.  No child is listed on the census.  I have no information on the father listed on James's birth certificate.  Hard to track B. B. Wooten aka Bill Smith. 

My current effort is to trace the relatives listed on the death certificate of Ada M. Hughes.  Any other thoughts or suggestions are gladly accepted.
