John Hass/Hattie Haas - Son John Haas 1909

I'm looking for the family of John and Hattie Haas (nee Wallace). John Sr. born 1884 in Kansas. Hattie Born 1889 in Missouri. I found Hattie and John together in the 1930 Missouri census with Hattie's parents, Albert and Hulda, living with them. In 1920 their son John was in Kansas. I don't know if he said in Kansas or moved with his parents back to missouri where John and Hattie met.
