The Kom descent charter begins with the eponymous ancestor kom and branches out to encompass the various agnatic descent groups. The charter down to the beginning of each separate descent group is shown below. In this and subsequent descent diagrams the scale on the left indicates the number of generations above that of current young adults (generation "0" = 1980 A.D.) in the longest generational line. Corresponding dates are, of course, rough approximations to reality, calibrated where possible to coincide with known birthdates. Outside of such calibration, dates are calculated based on a generation of 20 years, which accords well enough with observed rates.

It is not uncommon for a man´s sons to be born a generation apart to different wives. The cumulative effect of such late progeny may produce a disparity of several generations between agnates of senior and junior lines. Since kinship terminology is generational, such a disparity may require a grown man to reckon a toddler as his "grandfather" (vov).

The earliest part of the charter contains what appear to be names of significant places. kom is the etymological descendent of kâmâ, the name of the region at the confluence of the Kunar and Kâbul Rivers where the Kom lived a thousand years ago. Five undoubtedly collapsed generations later is the name âT'ol ‘Cliff', sometimes even given as kâm'aTol ‘Kom Cliff', which is the name of the place from where the Kom came to their present location. One of âT'ol´s sons was piT, which means both ‘ridge' and ‘wooden part of a bow'. The former meaning could refer to "Clay Ridge" (pâm'uRipiT), the site of present-day KombRom. Thus, encoded in the charter may be an indication that the Kom migrated to their present site some 23 generations ago, or around 1500 A.D.

Using this assumption, I have placed the ancestor of kâñ'a´s (‘Blind One´s') Boys in the same generation as piT. Their precise linking in the charter is unknown, but they are reputed to be the descendents of a Kom´s marriage to the daughter of the blind Jâši leader who remained at Clay Ridge when the Kom took it over.
