Sucken
The 'Sucken' was the area over which a mill held thirlage over tenants and a 'suckener' was a tenant thirled to a particular mill. The millers were obliged to enforce the adherence of tenants to the thirlage laws, as the income of the miller was based on that portion of the tenants' grain that the miller was legally entitled to take for the act of milling the grain. The legal term 'astricted' was applied to a tenant who was thirled or bonded to a particular mill. The term 'Out sucken' was given to a mill which ground corn from outside its thirl or sucken for whatever reason.
