A wife is a help mate. Why does a man need to have a house in place before finding a wife? If you live in a one bedroom apartment, that is enough to start a family.
There is a little 2 story cabin I drive pass sometimes. It is 200 square feet and it housed a family of 10 in like 1780.
That’s a really cute cabin. I wouldn’t at all mind living in it. With 10 children? Maybe a bit tight, but I’m guessing they had very minimal furniture and belongings. It probably has a loft where one could put out some hay under canvas and sheep wool blankets. With the fire going, wool, hay, and body heat, it’d be pretty cozy.
