Laufey

"Laufey is common Icelandic female name"
Laufey or Nál is a figure in Norse mythology and the mother of Loki. The latter is frequently mentioned by the matronymic "Loki Laufeyjarson" (Old Norse 'Loki Laufey's son') in Eddic poetry, rather than the expected traditional patronymic Loki "Fárbautason" ('son of Fárbauti'), in a mythology where kinship is ideally reckoned through male ancestry. 
Name.
The meaning of the Old Norse name "Laufey" is unclear, but it is generally taken to be related to "lauf" ('leaves, foliage'), perhaps attached to the suffix -"ey" (found in female personal names like "Bjargey", "Þórey)", or deriving from an hypothetical tree-goddess named "*lauf-awiaz" ('the leafy').
Since the name of her spouse "Fárbauti" means "dangerous hitter", a possible natural mythological interpretation has been proposed by some scholars, with lightning hitting the leaves, or needles of a tree to give rise to fire.
Attestations.
In "Gylfaginning" ('The Beguiling of Gylfi'), High introduces Loki as the son of Fárbauti, that "Laufey or Nál" is his mother, and that his brothers are Býleistr and Helblindi. Elsewhere in the same poem, Loki is referred to by the matronymic "Laufeyjarson" ('Laufey's son'). This occurs twice more in "Gylfaginning" and once in "Skádskaparmál".
"Skaldskaparmal" ('The Language of Poetry') mentions Loki as 'son of Fárbauti' or 'son of Laufey'.
Laufey is listed among Ásynjar (goddesses) in one of the "þulur", an ancestry that perhaps led her son Loki to be "enumerated among the Æsir", as Snorri Sturluson puts it in "Gylfaginning".
"Nál" is mentioned twice in the Prose Edda as "Laufey or Nál"; once in "Gylfaginning" and once in "Skáldskaparmál".
In the poem "Sörla tháttr", Nál and Laufey are portrayed as the same person: "She was both slender and weak, and for that reason she was called Nál [Needle]." According to scholar John Lindow, however, "the late date of the text makes this piece of information suspect."
