It is always thrilling to find a new record. I’ve found Edna Michael, wife of Fred Michael and the sister of John Aumack in the Michigan, Pipestone County (corrected – this should be Pipestone Township, not county) (pg 15) 1940 census.
Fred Michael, head of household, age 63, farmer (owned his own farm)
Edna Michael, wife, age 59
Walter Michael, son, age 22 (assistant farmer).
All born in Michigan.
