Sorry for any confusion Lisse: when I say Primary World sources I mean 'Real World' sources, like Kalevala, or the Poetic Edda.
Hmm, now I've got to remember what I've read so far in Kalevala about braids. Hard to recall at the moment so I'll do a quick search on the interweb; but I do generally remember the reference 'braid-head' like in the translation given below these first two examples...

On my breast no golden crosslet,
In mine ears no golden ear-rings.'
