ceasg is a freshwater mermaid, though little beside the term has been preserved in folklore. Mermaids from the Isle of Man, known as ben-varrey, are considered more favorable toward humans than those of other regions, with various accounts of assistance, gifts and rewards. One story tells of a fisherman who carried a stranded mermaid back into the sea and was rewarded with the location of treasure. Another recounts the tale of a baby mermaid who stole a doll from a human little girl, but was rebuked by her mother and sent back to the girl with a gift of a pearl necklace to atone for the theft. A third story tells of a fishing family that made regular gifts of apples to a mermaid and was rewarded with prosperity. In Irish lore, Lí Ban was a human being transformed into a mermaid. After three centuries, when Christianity came to Ireland, she was baptized. The Irish mermaid is called merrow in tales such as "Lady of Gollerus" published in the 19th century.

Wartburg (Gorog tr.) glosses navette" as "sort of water-sprite (ondine) which attracts passers-by at night.. and plunges in with them", adding that in the patois of Valognes, it is used as a bugbear to frighten children from approaching water.}} An early description of the Havfrue, and her mate Havmand, was given by the Dano-Norwegian Bishop Pontoppidan (1753). They were considered the mating female and male of the creature, inhabiting the North Sea, and their offspring was called (var. ), as repeated by later commentators. Though he was aware of fabulous fables being told about them, he was convinced such creature existed. But as they were non-human, he argued the term Havmand (merman) should be avoided, in favor of some coined term such as sea-ape
