Some like 'em young...

[SwissBarbar]

actually for a girl of the roman high society it would be a shame not to be married. Girls were given away by their fathers with 12-14 years, boys with 18. A marriage was a partnership of convenience, mostly planned by the parents years before the actual wedding. Infertility was one of the grounds for divorce. Feelings dit NOT matter! Actually, love as a reason of wedlock is a very young phenomenon in history of civilization.

in my opinion, the fact, that girls were mostly named after her fathers family name - at least in the time of the republic (gaius iulius caesars daughters name was iulia, the daughter of Gaius Antonius Hybrida was named Antonia etc.etc) shows that they were his property, so he could marry them to whom seems best for the family
