In the 1930 census, there was William A, Elfreda M, and Frances E. living in the household
In the 1940 census, William was 52, Elfreda was 49, Phllyis, 20 who is actually Frances ( I suspect sometimes the enumerators heard or spelled names incorrectly) and married to Edward Johnson (should be Johnston), 24. They are all living with William and Elfreda, Frances parents.
