So, I have a snippet (called Earl Brand / The Seven Brothers) collected by Fanny Eckstorm here in Mattawamkeag, Maine in 1928 from Mrs. Guy Hathaway.

Any thoughts about it's pedigree? Also, I have read some interesting stuff tracing this to a medieval Norse saga about Hildebrand...)

Rise up, rise up, ye seven brothers all
And put on your armour so gay
And take the care of your elder sister
For the younger I'll carry away
