Cockett Family History

English:: in Lancashire and Yorkshire: habitational name from Cocket in Rathmell (near Giggleswick, Yorkshire). In southeastern England: variant of Cackett, a habitational name from Cacket's Farm in Chelsfield (Kent), which was earlier recorded as Caldecote.

Possibly also from a pet form of the Middle English personal name Cok + the diminutive suffix -et. Compare Cocklin. Alternatively, a nickname or occupational name for someone who carried a seal, such as a customs officer, from Middle English coket, Old French coquette ‘seal’.

Nickname for someone who liked eating bread made of fine flour or one who baked and sold it from Middle English coket, so named (it is doubtfully supposed) because the bread was stamped with an authenticating seal.
