Actually, I'm pretty sure "family" is the subject. "Four" is the object of the preposition "of". Props to the OP to start the most lively discussion under this column over such a pedantic and yet unfounded criticism. I'm probably more interested in how I can earn $6206 on the internet so I can buy a a great new Subaru Impreza. i suspect that is a specious claim… Great day and Happy New Year to all.
