filbert: [14] Hazelnuts begin to ripen around the end of August, and so in medieval times they were named after Saint Philibert, a 7th-century Frankish abbot whose feast day falls on the 22nd of that month. Thus in Anglo-Norman they were *noix de Philibert or noix de filbert – whence English filbert.

"hazelnut," late 14c., from Anglo-French philber (late 13c.), from Norman dialect noix de filbert, in reference to St. Philbert, 7c. Frankish abbot, so called because the hazel nuts ripen near his feast day, Aug. 22 (Old Style). Weekley compares German Lambertsnuss "filbert," associated with St. Lambert (Sept. 17); also German Johannisbeere "red currant," associated with St. John's Day (June 24). The saint's name is Old High German Filu-berht, literally "very bright."
