Temporal identity

So I’m returning to this idea again, which I first floated back in September over here, of temporal identity. I’ve still not really seen it explored anywhere, but I do think it’s potentially a valuable methodological approach. 
The idea is to interrogate texts for a sense of identity defined with significant attention to one’s place in time.  This identity may be personal, or attached to membership of a small group (family, parish, social stratum), or on a larger scale approaching national or universal.  It may also involve the deliberate exclusion of other groups (we are more advanced / more traditional than they are), or an attempt to forge a more inclusive future.  It may be unconscious, assumed, or defensive of something that ought to be generally assumed; or it may be deliberately constructive of a particular historical moment.
For example, we know that (broadly speaking) some Renaissance texts could be found to define themselves deliberately against an immediate mediaeval past, particularly certain aspects of it that they found repellent or obstructive, and simultaneously assume to themselves similarities with a more distant classical past, in an attempt to construct (in collaboration with other people now) a more idealised future. 
Millenarians (which I know nothing about) could also be an interesting case in point, as investing (or professing to invest) an exceptional degree of identity in one clearly defined future point, beyond which there would be no future (or would there? how does divine/infernal eternity relate to this?).  But to what extent do they (individually - I doubt they were ever really a body as such) acknowledge a debt to the Biblical and classical traditions on which they were drawing, or relate the coming final moment to the sinful actions of the distant past, immediate past or present?  How did they understand the effects of one moment in time, or one age, on another, on themselves, on the world around them, on the moments to come?
Other potentially interesting fields of investigation:
- On a smaller scale, and prompted just now by thoughts of millenarians’ focus on a specific immediate future point: what about individual testimony within individual lives? such as a pregnant woman awaiting childbirth, if such a testimony exists? Could we extend this sort of investigation to such an intimate, complicated test subject?
- Genealogy. In every age that I’ve investigated there is a degree of interest in one’s ancestry to be traced, especially amongst the nobility for whom it can prove land claims and precedents.  We could therefore perhaps study it across several centuries to ask what it can reveal about changing temporal identities.  For example, who was interested in it at any given time? 1066 and the next generation or two doubtless provided a crisis in England for both the locals and the invaders in terms of tracing one’s bloodline and preserving a connection with the past – are there similar moments later on? What effect did it have? Was it exclusively or primarily a noble (or gentle) pastime until the late mediaeval/early modern times? and is pastime the correct word? How and when did it spread, and to whom? What was it used for? proof? of what? to what ends? And what could prove it? The Earl of Warren’s sword with which his great-grandfather helped William invade England? A diagram on paper shaped like a tree whose roots are literally in the bowels of William the Conqueror?
- What about ‘progress’? Whose idea is that? And I mean that in a continuous way – not ‘where did it originate’, which is not a helpful question, but ‘in any given generation, was the idea of progress present, and was it positive or negative according to any given member or group in a given population’.  Of what did it consist, where were the emphases laid, and did it give any sense of a continuum in which the past, via the present, informed the future? or was the past being discarded?
- Is there any particular polemic associated, at any given point, with temporal identity? Is it continuous enough to trace any sort of history of it? To what extent do people use temporal concepts as insults (and do they in that context have an implicit identity-forming function by contrast)? I imagine, for example, this might come up a lot in theological/academic argument – accusing someone of being outmoded, or of abandoning auctoritas, places a value judgement on intellectual temporalities (or rather, lends them a temporal angle).  Or to look at it another way, the age of an individual – Chaucer’s Januarie/May repeats a well-established pattern of despising the body of the aged in comparison with the fresh body of youth, but of course there is more to the discourse of age than that, and the compliment might often be reversed (wisdom of age vs folly of youth, etc).  And how does this alter when someone has died, is past?
- And of course, most interesting from my point of view – how does a person’s perception of their individual relation to history, of their age’s place within a broader (divine?) scheme, of their duty to a future time (and/or present patron) affect their perception of their immediate task when they sit down to write a chronicle, write history? And what else gets in the way?
