What would happen if let's say, two people courting in Victorian England had sex, and the woman ended up pregnant? Would their respective families force a quick marriage?
Among the lower class, or servants, were they more likely to "date" in the modern sense of the word since c'mon, I'm sure their lords wouldn't care if some servant was having sex outside of marriage.
Premarital pregnancy was rare among the upper classes, because girls were chaperoned and their activities controlled.
In the middle classes it was fairly rare, and the girl was swiftly married to her seducer, or sent away to give birth secretly and the child adopted.
Many working class women became pregnant outside of marriage; however, because of the social stigma, the fear of losing their paid work, and lack of money to raise the child, many concealed the pregnancy.
If, as was common, a domestic servant became pregnant as a result of seduction by her employer, sometimes the family expelled the girl from the house, but if the seducer was working class the couple was often pressured into marrying.
