The wikipedia definition of a deserted medieval village (DMV) is a former settlement which was abandoned during the Middle Ages (around 500AD to 1500AD), typically leaving no trace apart from earthworks or cropmarks.
Several potential DMVs are thought to be in Lichfield and the surrounding area (there are over 100 for Staffordshire as a whole).
Here is selection from the Staffordshire HER. 
Tamhorn Deserted Settlement, Fisherwick
Curborough
Littlebeech, Lichfield (Saxon, mentioned in Domesday)
Farewell
Horton, Fisherwick
Stychbrook
Elford
Swinfen
Freeford
Abbots Bromley
I hope to have a look at these in more detail and to post updates shortly!
