_Etymology of "Grasson"_ (Vol. iii., p. 8.).--Grasson appears to be derived
front "grassor," "to assail." Livy somewhere has the following--"Grassor in
possessionem agri"--which would be rendered, "To enter upon it by force;"
it being only by the payment of the fine (Grasson) that the entry,
"Grassor," or alienation of copyhold lands, could be warded off: hence the
act of the lord of the manor (Grassor) became the name for the fine paid by
this tenant, "Grasson."
