Dear Shri Gopalaswamy,
Your doubt is not clear to me especially the reference to "(-4) earlier generation". Do you mean to say that tarpanam for the 3 earlier generations? Anyway my reply is given below:
Since you seem to be having some doubts about the need for propitiating more than three generations of pitr^s, I may state that a firm believer in the doctrines of karma, punarjanma and karma-vipaaka may find it difficult to reconcile those doctrines with the belief that by offering balls of rice to his three deceased paternal ancestors, a man will be able to bring gratification to the souls of the latter. Such basic doubts existed even in those times. But it will become a very long post if I have to deal with all that.
You are apparently not one with such basic doubt about the need for Sraaddha itself, I suppose. The pitr^s, in theory are infinite in number going backwards till the beginning of one's gotra. But considering practicalities , we have taken only (as per Apastamba's gr^hyasutra as well as those of some others) the three generations preceding the person concerned. FYI, some Maharashtrian brahmins perform tarpanam (and also Pindam, I am not sure about this point but) for 7 generations.
Since you have asked for references, in SAtAtapa smr^ti twelve groups or divisions of pitr^s are mentioned viz., piNDabhAjaH (3), lEpabhAjaH(3), nAndeemukhas(3), and aSrumukhas(3). The Matsyapurana says that 'ancestors from the fourth (i.e., father, grandfather and great-grandfather of the performer) are entitled only to the wipings of the articles of food (sticking to the hand of the SrAddha performer); the father, the grandfather and great-grandfather are entitled to piNDa; the offerer of the piNDa is the seventh; thus "sapiNDa" relationship extends to 7 generations and this has been followed by almost (I suppose) all the smr^tis.
The mArkaNDeya and brahma puranas state that the lepabhAja pitr^s are entitled to enjoy the wipings (lepa) of the hand of the performer when he offers the piNDas.
Hence, if once we believe in the tarpanam and sraddha rites, it is better to follow the prescribed rules.
