10 Domesday destinations you can still see today

Wooten Wawen

The pre-Norman tower of the parish church in this Warwickshire village. The book says: "There are 23 villans with a priest and 22 bordars having 6 ploughs. There are 2 mills rendering 11s and 8 sticks of eels... It is worth £4."

Can someone explain the use of the word "villan" in this excerpt? I realize it is another form of villain, but in this context does it mean that half of this village is populated by bad guys? And why is there a priest with them?
