@TheRegencyCook Nr., for "near".
Fairly common to put "Smalltown, Nr. Bigtown" in postal addresses even 30-40 years ago, so not surprising if they did the same at the house/street level in the 1920s.
@JoshuaLisec Lightyear actually failed at woke. Two white men decide a black woman should pursue motherhood over career, and make this choice for her without her knowledge or consent.
