In a book about Roman onomastics I came across a reference that mentioned in passing that the samoyedic people didn't give personal names to their women, but when I traced the reference it ended up in unsubstantiated hearsay (for anyone wondering, the source is Schulze, Zur Geschichte Lateinischer Eigennamen, Göttingen 1904, p. 51 f. 5.) Schulze there makes the claim that, much as Roman women had no personal names in a legal sense (viz. there only were distinctions like 'the tall one', 'the small one' and so on), the samoyedic women had, in fact, no names: "...bei den Römern die Frau seit alters her rechtlich namenlos war, wie sie es bei den Samojeden tatsächlich gewesen sein soll." Italics mine - he says 'gewesen sein soll', so he's practically referencing hearsay. I find that a bit far-fetched, but maybe there is something to it, this would interest me (the topic of Roman feminine personal names is a bit contested on that issue). Didn't find anything about it, so far.
