I think these are the records of the Danziger births in Poland from the Radom Guberna.
The people match our family, but the dates of birth are off by a couple of years compared to Maer's dates on his Petition for Naturalization, which are later than the Polish records. Why might that be?

Images of the documents may be available at one of the FamilySearch Family History Centers. The closest one to me is the Essex Vermont Family History Center. It is right next to Temple Sinai on Swift Street, a pleasant walk from here.
I transcribed the records to a spreadsheet. Here is the image:
All the Polish birth dates are a little earlier than Maer reported on his Petition for Naturalization :
I have put the identifications in the Comments column of the spreadsheet.
Elja Majer is Maer.
Rojzla is Rachel Necha Goldberg, Maer's wife and our great-grandmother.
Abram Icek is Grandpa Abe Danziger.
Chawa is Hannah.
Maria is Miriam Paris.
Malka is still Malka.
Szmul Wewe is most likely William S Danziger
Fajga is Frances Cohn, born in R for Radom
Chawa Eta is Ethel Zuckerman born in Warsaw.
Elka Wajcman is Ella Weiczman, our grandmother. The Chawa Eta in Ethel's mother box is probably a transcription error.
Now we have the names of Maer's parents: Icek/Isaac Danziger and Chawa Łaja Sztern/Stern.
(I looked up the translation of Łaja and I got Laya or Leah, which is my mother Laura/Lucy Danziger Jacobowitz's name.)
