I have checked the 1930 census with no luck for Wallace Ellsworth or Avery & Helen Bullis. Could you check a city directory for them, as Helen died 16 May 1941 in Liberty. They just dropped off the face of the map. Her last son (William)was born in 1927 in Downsville(adopted out). My last hope would be a probate file for Helen, perhaps she mentioned her son William in the paperwork. Any help would be greatly appreciated.email: bumpie6@bresnan.net
