Sophia,

You want to find the family on census, vital records, passenger manifests, naturalization records, WW1 draft cards and the WW11 "old man" draft cards, etc.  These records can be searched online at the free site
www.familysearch.org
and on 
www.ancestry.com

Check if your local library has an Ancestry subscription.  Ancestry is allowing access on home computers through the end of December.

This is their 1923 Ohio marriage record with Max and Anna's parents names.  Obviously, the parents names are Americanized.  You may find Max and Anna's Hebrew names and those of their fathers on their tombstones.  That info will help you to find passenger manifests, and once you find their towns of birth knowing the Hebrew names will help you find records from there.

On the 1940 census the surname transcribed HEFFMAN.
Eldest 2 children born OH, youngest born MI.  So, they came to MI between 1927 and 1931.  That info will help you to focus your search, especially since the name is so common.

You can view the full census page, with much more data, on either of the sites I mentioned above.

There were two Sanford HOFFMAN's in Detroit at the time.  Their parents names are different though.  

I'm sure as you search further that you will find documents that give you Max and Anna's towns of birth.

Towns in Eastern Europe and The Russian Empire changed country often, and usually went by several different names in various languages.  Once you find a town of birth written somewhere you can search for the town and it's modern name at:  https://www.jewishgen.org/Communities/Search.asp

Hope this info helps you in your research,
