Churches supported them with food and connections to people who needed their services.
If they had homeless people in the community, people were of much greater character and would stay with friends or move in with other family.
Home ownership and living with only one family under a roof is a recent deal and more people were not professionals and were renting with several people in the past.
No one even back then had to starve or go without a roof over their head.
There were some shelters as well.
The mothers, and grandmothers like today that were alive helped out as well.
People IMO had closer family ties back them with less TV and computers.
Many children went hungry, they lived on Potatoes potato soup Potato everything so they would feel full
No welfare or Social Security back then, Many people dirt poor.
