Of Possessive Cases and Spatial Noun Roles

[alice]

Not sure if this should be here or in C&C, but anyway.

Let us postulate a language in whose earlier stages there was one noun role which denoted location ("locative") and another which denoted source or origin ("ablative"). Now let us postulate that from these roles the language developed two cases for possession, one for alienable possession ("genitive") and one for inalienable possession ("partitive"). So, we could have:

locative -> genitive, ablative -> partitive

or:

locative -> partitive, ablative -> genitive

Is one of these more likely to occur than the other, whether statistically (i.e. "more languages do it than the other") or conceptually ("the meanings are more similar this way round)?

FWIW, I understand that Finnish lends support to the first, but I may be wrong.

[Miekko]

Finnish partitive isn't used to mark possession, nor alienable or inalienable.

[alice]

Finnish partitive isn't used to mark possession, nor alienable or inalienable.

In that case my memory is faulty

That would be bricka.
