Some unmarried (usually upper class) women in Anglo-Saxon times inherited land at birth. This, of course, lead to many arranged marriages for land. Not only on the bride's side, but also the groom's. These arranged marriages started very young, before anyone else could arrange the marriage and gain land. Sometimes parents arranged marriages that were solemnized while children were still in cradles. There are many cases of eight year olds marrying each other, as well as 14 year olds marrying seven year olds. Children were considered capable of consent to marriage at the age of seven, but marriages could be voidable, as long as a girl was under the age of 12 and the boy under 14. At these ages, kids could be rid of their marriage, but most were pressured to into staying in the marriage, because of the land opportunities.
Comparably, peasant women had their marriages arranged for them, though were better off than those of the upper class. Arranged marriages among peasants happened later in life, usually when women were in their twenties, and happened with men they knew. These marriages weren't arranged for land, but for money, cattle, etc.
An unmarried Anglo-Saxon woman ("femme sole") had the right to do business on her own, without husband or man. She was considered 'on par' with men. Not only was she able to hold land, but she was also able to make wills and contracts, and could sue or be sued.
