I have a vague recollection, someone will correct me if I am wrong, that prior to Parliamentary Enclosures, cottagers had a house and a small "garden" area but crucially had common rights to graze a few animals and collect other benefits from commons. They had no land in open fields but they may have worked for farmers sometimes if they wished, at harvest etc. One of the criticisms of enclosures was that people who had been independent lost their common rights and were reduced to becoming ag. labs., probably still living in their cottages.
