I agree with Tim Black on this :
Not that peering into one’s familial past is necessarily regressive. Being interested in where we have come from is understandable and sometimes even illuminating. Yet there’s something that nags about the family-tree obsession. Those who are truly rooted, as one social critic once noted, don’t need to search for roots. And that’s it, that’s the problem today. Bereft of better, future-oriented ways of thinking of oneself, of forming identities based on what one does and thinks and believes, of rooting oneself in the tumult of the present, too many root themselves in their ancestry, their cultural and biological backgrounds. As if all that, rather than the individual himself, is all-determinant.
