ME crud, crudde 'curd' is recorded by OED from 1362. In Suffolk I've noted a
Cruddemelne 1319 in Bures and a Cruddeslane 1325 in Ipswich. Are these named from the dairy product? I don't see the word in Smith's Elements, nor in the books of Field on field-names. Is a "curd-mill" plausible? The Ipswich lane is
complicated by the fact that Crudde is a recorded 13th-century surname in the town, but I believe this surname will be the 'curd' word.
