After a thousand years, it is highly unlikely that they know who is 
the direct heir of anyone. I don't think it's even possible to trace 
an heir over that many centuries. Everything about the Founders is 
shrouded in mystery and legend. The dates aren't even precise.

Actually, it's not that difficult to fathom, considering the average 
lifespan in the wizarding world is at least double that of muggles. 
Dumbledore is 150-ish and Madam Marchbacnks is old enough to have 
tested Dumbledore whenhe was a kid and both of these two characters 
are quite spry, and still working (not to mention D-dore can do a bit 
fancy styling with his wand such as in his office whenhe leaves the 
school and the fight in the atrium of the MoM).  This cuts down a 
century (to us muggles) into, at least half that time.  That and 
given the fact that Hogwarts has a magical quill that writes down the 
name of every magical child born, I think it might be quite easy to 
keep track of these things whenthe blood lines stay within the WW.  
It's when the blood mingles and diverges into muggleville and 
squibland that things may become hazy.  Books like "Nature's 
Nobility: A Wizarding Geneology" don't just write themselves--people 
obvioulsy find this important enough to write a book about it.  I'm 
sure the Black tapestry isn't the only one.....and who knows, they 
could certainly be self-updating ones that do the genetic links 
magically.

invention...blood is important....look what Volde did with it to be 
reborn!)
