According to the 1940 U.S. Census, Edwin "Pete" and Lela (Viets) Heiden lived at this address on South Custer Road with their three children, Donald, Deloris  and Glen (shown from Left to Right in that order below).

Edwin's cousin, Lester Heiden and his wife, Lila (Lela's twin sister) with their two children (Robert and Donna Mae) are listed next on the same page of the census. They were living as neighbors at that time before moving to a house several miles to the east at  7299 South Custer which is  across the road from the Heinrich Rambow family.

We do not know any further details about Lester and Lila's home at that time. If you have information to add, please EMAIL.
