Does magic run through bloodlines? For example, could my Ouramancer come from a line of such Magestrava, with the talent skipping generations every so often?Is it more metaphysical than that?

Magic is more of a mutation in the normal populace, while Ouramancers need bloodline and history to be born with the talent - but yes, they can come from a line of Magestrava, so long as there is indeed Ouramancer blood somewhere there.
