Today I discovered the story (a story...??) of Saint Valentine. San Valentino was born in 176 and became the bishop of Terni in Umbria. It was the practice that families with girls of marriageable age provided a dowry. Without a dowry, a girl had little or no chance of marrying. So San Valentino gave money to girls from poorer families so that they were able to provide a dowry and hence find a suitor.
I don't know if this is true but I like the idea!
