What did a serf's family look like?

On a more serious note, you'll have to be more specific with your question. Peasant/serf family structures often varied from region to region and era to era. Beyond the basics (large families, subsistence farming, etc) its hard to draw a general picture

Well, I don't really have anything specific in mind.
