I created this mnemonic while working with the 12 Handmaidens of Fensalir in the setting of an inclusive women's group. I'm not sure where to put Huldra, as I have understood the Huldrafolk as a kind of being, not an individual goddess, and thus have not approached the question yet within this framework.

North - The Path to Home: Hlin who guards the perimeter, Gna who communicates with outsiders, Syn who stands at the threshold.

East - The Path to Knowledge: Saga who tells tales, Fulla who guards secrets, Vor who sees all.

(Alternately: Saga who keeps histories, Fulla who keeps secrets, Vor who keeps mysteries.)
 
South - The Path to Happiness: Eir who teaches us how to live, Gefion who teaches us how to receive, and Snotra who teaches us how to
 behave.
 
West - The Path to Love: Siofn who creates affection, Lofn who gives permission, Var who hears our vows.
