Ancestral Experience Stories

Books that reflect my ancestors' experiences in the world. The likely ethnicities you may find in this list:
* Jewish
* Irish
* Scottish
* Welsh
* Scandinavian (with an emphasis on Norwegian and Danish)
* German
Likely subjects:
* Immigration to America in the early 1900s
* Racism in America, particularly against Jewish or Irish immigrants
* The Holocaust

Not an extensive list, but some I'm definitely likely to be finding books about.
